TSP-020202 Temperature Sensor for Boiler
The temperature sensor for heat exchangers and hot water generators only contains a small amount of material, thus having a low heat storage capacity. This means that the medium to be heated changes its temperature rapidly. Under these conditions, fast-re-sponse temperature sensors must be used to guarantee stable temperature control. The Type TSP-020202 Temperature Sensor has proven well for this purpose, since it has the following features:
- Optimum transfer function featuring a half-time t05 of 0.75 s and a nine-tenth time t09 of 2.3 s for measurements in flowing water
- Minimum thermal resistance and low heat capacity
- No air space between measuring insert and immersion tube
- Blow out safe sensor tube, immersible between 60 and 240 mm.
The transfer function gives information on the good thermal conductivity of the sensor. This function is a time characteristic representing the measured value after a step change in the measured variable.
Fast-response temperature sensor. Immer-sion-type sensor with Pt 100 resistor. Measuring range 0 to 120 ° C. With 300 mm tube; immersion depth 60 mm (min.) to 240 mm (max.); free cable end 2.5 m. Accessory: Screwed gland G 3⁄4.
Application
Fast-response temperature sensor for measuring rapid changes in temperature in heat exchangers and hot water mixing circuits. Pt 100 measuring resistor. Basic values are according to DIN IEC 751 (DIN 43 760).

Principle of operation
The Type TSP-020202 Fast-response Temperature Sensor is a foil sensor containing a platinum winding which is embedded in two 0.05 mm thick polyamide foils. The measuring insert is located inside the immersion tube having direct physical contact with the thin tube walls. For electrical connection, a 2.5 m cable with free cable ends is available.

In order to guarantee short response times, the sensor is to be immersed as deep as possible into the medium to be controlled without being protected by an additional tube.
The larger diameter of the disc type sensor tip prevents the immersion tube from sliding out of the screwed gland.
Temperature Sensor with Pt 1000 Resistors
Application
Sensors for measuring temperatures in heating, ventilation and air-conditioning systems. Versions with Pt 100 measuring resis-tors. Basic values are according to DIN IEC 751.
1) Depending on the instrument connected
2) For duct sensors, flange connection instead of G 1⁄2
3) Approx. 0.23 kg for 80 mm thermowell; approx. 0.25 kg for Additional thermowells required 250 mm thermowells
Note
The temperature sensors are connectable in two-wire or three-wire circuits. Connection procedures and line balancing are to be performed in accordance with the requirements of the con-nected controller.
The lines connecting temperature sensor and controller are to be installed separated from the lines conducting system voltage.

Fast-response Temperature Sensors with Pt 1000 Resistor
Fast-response temperature sensors are used in compact heat exchangers and domestic hot water generators which only contain a small amount of material, thus having a low heat storage capacity. This means that the medium to be heated changes its temperature rapidly. Moreover, the temperature sensors are easy to install and do not need any adjustment.
