Freeze protection of pipelines and vessel
The electronic temperature controller is designed to maintain the temperature in the set range.
PT-300 is used in general-purpose industrial electric heating systems of pipelines and tanks, in de-icing systems, as well as for maintaining a positive temperature in control cabinets within the set temperature range. The required temperature range corresponds to the selected pre-programmed TST04 temperature sensor.
The sensor is programmed at the factory and cannot be reprogrammed.
The regulator, in conjunction with the connected temperature sensor TST04, maintains the temperature according to the factory setting and does not require any settings for installation and operation.
The on/off button allows to switch off the heating system when it is not needed.
