Product Description

4327021 Diesel engine parts Temperature Switch NT855

Product introduction

4327021 Diesel engine parts Temperature Switch NT855The water temperature and water level sensor is composed of a thermostat part and a water level control part, and is heated in cooperation with a pressure reducing device and a rotary muffler heater in front of the electric valve. The water level sensor in the container transmits the sensed water level signal to the controller, and the computer in the controller compares the measured water level signal with the set signal to obtain the deviation, and then according to the nature of the deviation, sends out "Open" and "Close".”command to ensure that the container reaches the set water level.

Product feature and application

4327021 Diesel engine parts Temperature Switch NT855, the temperature control part of the computer sends an "open" command to the electric valve that supplies the heat medium, and the system starts to heat the water in the container to the set temperature. Only when the controller issues the command to close the valve and cut off the heat source, the system enters the heat preservation state. , During the programming process, it is ensured that the electric regulating valve that controls the heat source will not be opened when the system does not reach the safe water level, so as to avoid heat loss and accidents.
