Product features Temperature probe with stainless steel connection head and RS485 output

DESCRIPTION AND APPLICATION

All of this temperature sensors with RS 485 output are intended for contact measurements of the temperatures of liquid and gaseous substances. The standard temperature range in which the sensors can be used is between -50°C and 150°C. The sensors meet the standard IP 67 in terms of protection against infiltration, in accordance with standard EN 60 529.

The sensor - central support combination is suitable for measuring the temperature in air conditioning ducts. The sensor-thermowell combination is suitable for temperature measurement in pipes.

The composition of the sensor material of temperature complies with the requirements of Decree 38/2001 Coll. as modified, and the design of the sensor also allows a easy cleaning. Thanks to these properties, it is possible to use the temperature sensors in the food industry. The sensors can be used for all control systems compatible with the ModBus RTU communication protocol.
