RS PRO PT100 RTD Sensor, +70°C Max

Thermistor and Pt100 type sensors in a variety of packages suitable for use with most air conditioning control systems.

Sensor Types:
Thermistor: direct thermistor (NTC) temperature (10kΩ at 25°C) versions. These are degradable components and should be replaced on a 2-3 year cycle.
Pt100 sensor: 2 wire sensors with brass probes providing a linear response and positive temperature coefficient.

Package Types:
Space Air (813-806; 376-1477): a white ventilated unit for interior use, temperature range -10 to +60°C.
Duct Air (813-862): an IP65 housing with 20mm conduit entry, 210x19mm dia. probe with fine mesh gauge for sensor protection, temperature range -10 to +60°C.
Outside Air (813-828; 813-878): an IP65 enclosure with a small brass cap, 20mm conduit entry, temperature range -10 to +60°C.
Liquid Immersion (813-834; 813-884): an IP65 enclosure with 20mm conduit entry, 130x6mm diameter brass probe which fits into a brass pocket (available separately) for a temperature range of -10 to +60°C
Pipe-Clamp on (813-840; 813-890): a sensing element located in a lug which is fitted to the pipe via a stainless steel cable tie. IP65 terminal with 1m of cable, maximum temperature 110°C.

The brass and steel pockets have grub screw probe fixing for easy replacement.

Different industries need different solutions to keep up with the evolving world. If humidity and temperature are in play, Humidity/Temperature Transmitter seems to capture both requirements to support many applications. Merging both strengths, the Sensor can meet the specific demands of temperature-sensitive devices.

Those popular products have their place across everyday life situations, from the apparent objects in our home, such as kettle or toaster to more advance applications including monitoring the temperature in alcohol breathalysers or maintaining temperature for equipment to fabricate medical drugs. Still, the key message is the responsiveness and accuracy of the detection circuit is essential for quality control.

We are proudly introducing our own branded RS PRO Temperature Sensor for Air Conditioning for use with most air conditioning control systems. This Air Sensing Temperature offers an impressive range from – 30°C to + 70ׄ°C providing a reliable operating temperature scale for the external application. The 2-wire Sensor with brass probes accelerates a linear response and positive temperature coefficient.

You do not have to pay a premium price to get a professional quality part as our engineers testified our Transmitter so that you can purchase with full confidence.

Depending on sensor types and package type requirements, you can check the following options:

Sensor Types:

• Thermistor: direct Thermistor (NTC) temperature (10 kΩ at 25°C) versions

• PT 100 Sensor: 2 wire sensors with probes providing a linear response and positive temperature coefficient

Package Types:

The Temperature Sensor/Transmitter with a diverse range of industries across multiple sectors makes them desirable in:

• Cleanroom monitoring


• HVAC (Heating Ventilation, and Air Conditioning)


• Ideal for applications where space is at a premium


• Use with building management systems


• Home appliances


• Drug industry

How long does Humidity/Temperature Sensor last?

Depending on how the unit is getting maintain along with the effectiveness of parameters will determine life expectancy. The average estimated life of a Temperature Sensor should last around seven to ten years.
