Product description
Automatic switch for two electrical appliances. Especially for DIN rail mounting. Fitted as standard with a 2 meter long Pt1000 sensor (extendable to a maximum of 50 metres. PT1000 sensors work without a power supply and are also accurate if you extend the 2-wire connection cable. The switching temperature is adjustable in steps of one degree Celsius. The display temperature shows 1 number after the decimal point. This temperature switch is very easy to operate. It can also be used as a thermometer and has a memory for the highest and lowest measured temperature. The adjustment range of the temperature controller is large. This means it can be used for frost protection, but also for all kinds of applications with electric heating, including heating cables.
Applications
Adjustable hysteresis
The switching accuracy is freely adjustable from 0.1 °C … 10 °C. Application examples DIN-rail temperature switch Pt1000: Replacement for defective thermostats in heating systems, as backup control for air conditioners, for monitoring and controlling temperatures, for example in the production of beers and spirits or in the greenhouse for temperature-controlled ventilation. When using frost protection, the connected device or heating ribbon will only receive mains voltage if the ambient temperature is lower than the switching temperature set by yourself. A value of 3 to 5 °C is usual. You can adjust this very easily.
Memory for set values
The DIN temperature switch has a memory for the settings. All menu values are retained when the mains voltage is lost, even if you remove it from the socket. There are no LED indicator lights, but you can read the current temperature, among other things, on the display. Furthermore, this temperature switch gives an error message if there is a problem with (the cabling of) the sensor.
