Ametek STS Series temperature sensors are high quality instruments for use with Ametek DTI-1000 and DTI-050 digital temperature indicators. These systems are ideal for industrial temperature calibration applications where accuracy and long-term stability are important.

Ametek STS Series temperature sensors are economical and offer fast response times, low immersion depths, compact physical sizes, and specified low drift rates: even at high temperatures. These are all important considerations when selecting a reference sensor. In addition to straight sensors, Ametek STS Series temperature sensors are available in a 90° angled version specifically developed for use with dry-block temperature calibrators. The Ametek STS Series temperature sensors allows both the sensor-under-test and the reference sensor in the thermowell at the same time.

Ametek STS Series temperature sensors are available in three primary models to suit most applications.

Ametek STS-050 Temperature Sensor

The Ametek STS-050 temperature sensor is an intelligent sensor that can automatically read calibration data and sensor type from a memory chip placed in the sensor. This makes it possible to change the sensors used without re-programming the temperature indicator. When an intelligent sensor is connected, all information about the sensor, such as serial number, calibration data, and coefficients is available and can be shown on the display. This Pt100 sensor measures temperatures from -58 to 752°F. Hysteresis @ 32°F is 0.02°F, and long term stability at 32°F is 0.025°F. The Ametek STS-050 temperature sensor is available in 4mm (0.16 in.) or 6.35mm (0.25 in.) diameters. This probe is 050 is for use only with the DTI-050 indicator and includes a carrying case, cable, traceable calibration certificate (6 points from -45 to 400°C) and user manual.
