It also cuts the number of RTD array connections (feedthroughs) from 4N to 4 + N. For 28 sensors, the resulting savings are 2N − 2 − N = 26 inputs and 4N − 4 − N = 80 feedthroughs.

The sensors feature 100, 120, 500, and 1000Ω resistance values. Available temperature coefficients include 6180 ppm, suiting DIN 43760; 6370 ppm suiting, the HVAC curve; and 6720 ppm, suiting ANSI ...

Omega’s new RTDM12 series of compact RTD temperature sensors are extremely rugged with a molded (IP67) 4-pin connector with M12 male thread and a fast response time. This RTD plug is ideal for ...

Vibration Resistant Thermocouples and RTDs The OMEGA PR-21SL RTD is built for use in thermowells and features spring loading to withstand contact between the probe and the thermowell in spite of ...

An earlier Design Idea described how to linearize the output of an RTD (resistance-temperature-detector) sensor and how to calculate the resistor values using a spreadsheet (Reference 1). That idea ...
