## About Cleveland Electric Laboratories

Cleveland Electric Laboratories describes itself as a family-owned business that has served customers for 100 years, under the heading "Advancing Sensing Technologies since 1920" and "Leading the Thermocouple Industry since 1920." Its stated mission is "to serve our customers with the highest level of customer satisfaction, providing competitive prices and products developed and delivered on time by our innovative, and empowered workforce" - the site uses the phrase competitive prices but publishes no actual prices, rates or fees anywhere. The published company timeline records: founded in 1920 to repair electric meters for railroad and Cleveland industries; Frederick J. Lieske became owner and President in 1954; Jack Lieske appointed President in 1981; new Twinsburg facility in 1986; ISO 9001 registration received in 2000; A2LA accredited for calibration services ISO/IEC 17025 in 2002; the Advanced Technologies Group (ATG) facility opened in Tempe, AZ in 2004; a series of fiber optic and sensing developments and patents from 2013 to 2016 including the Fiber Optic Rotation Position Sensor, a patented Fiber Optic Switch, a position sensor using Fiber Bragg Gratings, and a patented Sagnac Interferometer event sensing and locating device; and Scott Puhalsky appointed President in 2024. The quality certifications displayed across the site are ISO AS9100D Certificate, ISO IEC 17025 Accreditation and ISO 9001 Certificate, with certificate PDFs linked. The site does not break these certifications down by facility, and publishes no ITAR registration, Nadcap approval, security clearance, contract award, safety record or employee headcount. For questions about scope of accreditation, contact CEL directly.

## What Cleveland Electric Laboratories does

CEL's certification lab is described on the site as accredited to the international standard ISO/IEC 17025 and traceable to the National Institute of Standards in the United States, with thermocouple calibration certification standards meeting the requirements of ANSI/NCSL. The site states its automated data acquisition system is capable of certifying from -320 to 2800 degrees F, and lists technical data including ISO/IEC 17025 accredited, ISO 9001 certified, laboratory traceable to SI through NIST or other internationally recognised standards organisations, in accordance with ASTM specifications, AMS 2750 compliant, cryogenic temperature from -320 degrees F, and standard temps from 32 to 2800 degrees F. Repair and recalibration is split between facilities: at the Twinsburg facility technicians repair and calibrate temperature controllers and indicators used in high temperature industrial processes, and at the Tempe facility technicians repair, calibrate and manufacture turbine engine electronic test equipment. The lab also cleans and calibrates Lebow Torque Cell systems and provides a certification report, and calibrates temperature and process control instruments, indicating and recording instrumentation and DMMs. Exchange programs: CEL offers a precious metals exchange and reclaiming service so customers can return used thermocouples and receive new replacements at a reduced cost, though no figure, price, rate or percentage for that reduction is published. Engineering services include sensor design and configuration, sensor placement, 3D modeling, component modification design and instrumentation egress routing. Pricing for calibration and repair is not published; request a quote or estimate by contacting CEL.

## Where Cleveland Electric Laboratories works

Cleveland Electric Laboratories publishes two locations. The Arizona location, in the Phoenix metro area, is listed on the site as: 361 S. 52nd Street, Tempe, AZ 85281, phone +1 (480) 967-2501, email sales@cel-atg.com. This address and phone are specific to the Tempe site and are distinct from the corporate headquarters, which is located at 1776 Enterprise Parkway, Twinsburg, OH 44087, phone +1 (800) 447-2207 or +1 (330) 425-4747, email sales@cel-tcg.com. The Tempe facility is described elsewhere on the site as the Advanced Technologies Group (ATG), opened in Tempe, AZ in 2004. The site does not publish business hours, opening times, an appointment or booking system, or an online scheduling tool for either location, so anyone wanting to schedule a visit, book a call or confirm when the Tempe location is open must ask CEL directly by phone or through the contact form. The site also does not publish a service area or list of areas served, delivery coverage, or any statement that CEL travels to customer sites; it presents itself as a manufacturer serving customers nationally and by industry rather than by geography. The Contact Us page carries a contact form and the line "Start a Conversation About Your Thermocouple Needs." No prices, rates, fees or cost information are published for either address; pricing and any estimate come only from a direct quote request. A separate customer Certification Portal is linked for existing customers to access certification reports on demand.

Lists Frederick, Cleveland, Twinsburg, Phoenix, Tempe, and Enterprise as a location. Names Arizona, Ohio, and United States as a service area. Areas beyond these are not published.

## Thermocouples and temperature sensors CEL manufactures

The products and services page lists CEL's built-to-order line: VFT (Vacuum Furnace Thermocouple) assemblies, noble metal assemblies, high temp thermocouples, industrial temperature sensors, wire thermocouples, instrumentation, machining services and custom thermocouples. The site states that all MgO cable, base metal and noble metal wire is pre-tested, and that all steps of production comply with its ISO Quality Program, with its ISO/IEC 17025 certification lab performing testing as required to verify accuracy. Describing the range, the site says CEL offers "a comprehensive range of high-temperature and MgO thermocouples, including vacuum-sealed VFT, ceramics, and platinum thermocouples." Noble metal thermocouples are described as made from metals such as platinum and rhodium for high temperatures and resistance to degradation; platinum thermocouples are described as combining platinum with rhodium or tungsten. Custom thermocouples are described as precision-engineered sensors tailored to exact performance requirements for industries including aerospace, power generation and advanced manufacturing. The site does not publish a parts catalogue with prices, unit cost, rates or fees, and it does not publish lead times, delivery dates or production capacity. Customers choose a configuration by talking to CEL's application engineers and then requesting a quote or estimate; the site's calls to action are "Request A Quote" and "Contact a Thermocouple Specialist." Contact details and phone numbers for the Twinsburg, Ohio headquarters and the Tempe, Arizona location are published on the Contact Us page.

## Turbine engine test instrumentation services

CEL manufactures temperature and pressure mechanical instrumentation for the turbine engine test and development industry. The instrumentation page describes several distinct services. Rake and probe manufacturing: rakes and probes are manufactured to critical tolerances under strict process control, and can be designed by CEL's engineering team or built to customer specifications. Rake and probe refurbishment: CEL engineers and technicians evaluate the feasibility of refurbishing used rakes and probes and, where applicable, refurbish them for use as originally designed. Duct instrumentation: manufacture, assembly and instrumentation installation of turbine engine ducts and engine dress equipment, with attention to sensor placement and flow path profiles. Strain gauge work: technicians handle surface preparation, gauge installation and egress routing, applying foil, free filament, semiconductor and fiber optic gauge types in many configurations and sizes. Electrical slip rings: CEL provides and installs high speed slip rings (the page states up to approximately 100,000rpm) and FORJs that transfer electrical or optical sensor signals from rotating hardware to a data acquisition system. Engineering and design capabilities listed are 3-D solid modeling, instrumentation strategies, and rake and probe refurbishing feasibility analysis. No prices, rates, fees, cost estimates or turnaround times are published for any of this work; the page directs customers to contact CEL, and a quote has to be requested. Test cell instrumentation and rake and probe brochures are offered on the page as PDF downloads.
