MIST PTS02 Threaded Thermowell Programmabl Temperature Switch & Transmitter

Brand: Intempco Controls, Inc
Favorite

Series PTS02 is a Programmable Temperature Switch & Transmitter offering an Analog 4-20 mA output, transistor or relay switch output, and an optional RTD output. 

Utilizing Intempco’s patented MIST technology, PTS02 is designed for optimum accuracy and performance. 

The main areas of applications for this transducer are oil and gas as well as other hazardous areas. 

PTS02 is shipped factory calibrated to customer specified temperature ranges. But the unique feature of the PTS02 is that it is re-programmable. 

PTS02 is much more accurate than an RTD and a separate indicator / transmitter or switch. 

When the PTS02 is re-scaled to a different temperature range, the calibrated default values are not lost. 

This transducer can be re-calibrated by performing one-point or two-point calibration using known temperature standards. 

This is where the PTS02 leaves the competition behind. Indicating temperature range, current output, switch set point, switching hysterises, switch logic, damping and other features are all programmable.
