Customized PT100 RTD temperature sensor for HVAC pipe temperature measurement.

A customization case showing the application of PT100 temperature sensor for HVAC pipe temperature measurement.

We finalized the design of a PT100 Temperature sensor, which we customized for a customer from the UK last week. it is for an ambitious project of HVAC pipe temperature measurement .At the beginning we considered using a NTC sensor but later we found NTC is not linear, then we decide to use PT100, but the customer need to transform the output to 4-20mA, so a temperature transmitter need to add on the sensor. after hard work our engineer worked out the sketch as the following:

The transmitter is essential for this product, the sample was made today, it passed testing and work perfectly, we are getting ready for sending out the sample to the customer today .
