Temperature probes for heat meter

As a manufacturer, Testo Sensor GmbH produces temperature probes for heat and cold meters in accordance with specific customer specifications and, as an active member of the standards committee, also keeps an eye on all standards and guidelines for proper approval.

Consistently rising energy costs and strict legal requirements demand highly accurate billing of the thermal energy used in heating or cooling systems.

One important component of heat and cold meters used for this purpose are the precise temperature probes for determining the temperature difference at the flow and return of the heating or cooling system. 

Temperature probes for measuring the thermal energy, which are permissible for the demanding use in billing systems, are also available from us ready paired on request.

This is what distinguishes our temperature probes for heat metersOur certifications & standards

• EU type examination certificate according to module B of the guideline 2014/32/EU (MID) for heat meters
• Type examination certificate according to module B of the Measuring and Calibration Ordinance (MessEV) of 11.12.2014 for cold meters
• Recognised production quality assurance systems according to Module D of Directive 2014/32/EU (MID)
• Recognised quality assurance systems for production in accordance with Module D of the Ordinance on Measurement and Verification (MessEV) of 1.12.2014
• Suitability test according to the list of pronounced toleration of stockpile crushes
• DIN EN 61326-1:2013
• DIN EN IEC 63000:2019-05

Temperature probe pairing according to DIN 1434

We provide you the probes and on request also the pairing

Special guidelines and strict quality criteria apply to temperature probes in heat and cold meters. This makes the manufacturing process and especially the pairing process very complex. You can find a video with a small insight into our fully automated pairing process on our homepage.

We will show you how we have managed to make the process both effective and cost-efficient while still complying with all standards and specifications.

This ensures that we can not only meet the extremely high requirements of the PTB, but also significantly increase the sensor throughput per hour.
