ETI Industrial Thermometers by Ross Brown Sales

Supplier: Ross Brown Sales

Using one of three varieties of temperature sensors (thermocouple, NTC thermistor and resistance temperature detectors [RTD or PT100]), Ross Brown Sales’ ETI Industrial Thermometers are available in a number of unique models.

Price Guide: POA

Sensor types:

  • NTC Thermistors: NTC thermistor probes are also based on a temperature dependent resistance change in the sensor element. But unlike resistance thermometer detectors, thermistors have a negative temperature coefficient, ie, the resistance decreases with increasing temperature.
  • Resistance temperature detectors: Resistance temperature detector (PT100 or RTD) probes consist of a flat film or wire wound platinum resistance sensor element. The measurement resistance value changes in the line with the temperature being measured.
  • Thermocouples: Thermocouple probes consist of two wires of dissimilar metals or metal alloys welded together. Thermocouples are based on the thermoelectric effect. There are various types of thermocouple, types K and T being the most common.

The Therma Differential Thermometer allows the user to use two type K thermocouple probes simultaneously. The display can be switched to show probe T1 or T2 temperature or the difference between the two.

The PTR (Printing Temperature Recorder), printing thermometer has been specifically designed to provide a cost effective way of automatically measuring and recording temperature and time at regular present intervals.

There are various Bi-Metal Dial Thermometers that are ideal for industrial applications including waterproof, heavy duty and pipe surface thermometers.
