With a temperature probe and a suitable electronic unit you can regulate and control the temperature of your liquids.The temperature probes are equipped with Pt100 sensors.
Particularly in surface treatment, the precise measurement and control of temperatures is of decisive importance for the subsequent quality of the treated items. To keep the temperature of the liquid in storage tanks within the desired range, also prevents negative effects on the process liquids, such as freezing, crystallisation and excessive viscosity.
The following functions need to be implemented:
• Control of the temperature in order to automate process steps (such as keeping the desired process temperature)
• Monitoring of the temperature in order to avoid possible damage to the process, the process liquid (e.g. damage by excessive temperatures) and the tank (e.g. thermal damage) With the aid of temperature sensors and suitable electronic units, you can control and monitor the temperature of liquids easily and cheaply.
Our temperature sensors are available in the following versions:
• with rigid immersion tubes made of various materials
• with flexible tube made of PFA All versions can be equipped with one, two or three Pt 100 elements. Other temperature sensors specified by you can also be integrated. The function of the temperature sensor results from the integrated Pt 100 sensor element. The temperature is determined from the temperature-dependent change in the electrical resistance of the Pt 100 element. At 0°C, the element has a resistance of exactly 100Ω. As the temperature increases, the resistance of the element changes in direct proportion to the temperature change. A suitable electronic unit generates a low, constant current through the Pt 100 element and measures the resulting voltage across the element. The resistance of the element, and thus its temperature, can then be determined with the aid of Ohm’s Law (R=U/I). The connection between the electronic unit and the Pt 100 element can be made with 2, 3 or 4 wires. We provide 4-wire connections because these permit compensation for the resistance of the connecting wires. Particularly in the case of long wires, the measurement result can be significantly distorted by the wire resistance. Therefore, the connection of temperature sensors to electronics should not exceed 50m and should be executed generally with 3 or 4 wires. For longer lengths, it is possible to interpose a temperature transmitter with a standard output signal of 4…20mA
