Home > Temperature > Explosion Proof Temperature Switch
Series PTS02 is a Programmable Explosion Proof 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. Process temperature or alarm change? No problem! Simply use PTS02-PKIT interface module and re-range your PTS without the need to recalibrate and without the loss of accuracy. 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.
The PTS02 wetted parts, as well as the housing, are fabricated from 316 stainless construction. Other materials, various probe diameters, fitting sizes and thermowell types are available. For electrical connection, a 1/2” NPT conduit with lead wires is standard. The sensing element used is Pt-100 Ohm RTD Class A. PTS02 can be made available with an additional 3-wire RTD output. This feature allows a single process connection to be used for indication of temperature and for remote indication, recording, or controlling. Each PTS02 has the part number, range and serial number marked on the transmitter housing.
If you require an accurate, stable and dependable temperature transducer, look no further. Model PTS02 is your solution.

In all applications, especially those close to 200 ºC, careful attention must be placed on correct installation. It is the installer’s, customer’s and/or end user’s responsibility to make sure that this over exposure to temperature does not occur due to improper installation.
