Pressure transmitter winter freeze protection

In winter, the temperature is very low, in the instrument and meter industry also to pay attention to the freeze protection of pressure transmitter, don't know how do you do? Pressure transmitter freeze protection way is actually a lot of, the commonly used method is to heat tracing individual instrument antifreeze. Has steam heating or electric heating, if have considered winter climate factors of low temperature working conditions on site, so the selection should be considered when the supplementary insulation installation box. So what is a heat preservation box installation? Really insulation installation box is a box body, wrapped in pressure transmitter, the important element is heat preservation is the heater. Install thermal insulation box will be positive a socket, convenient power on. Here need to add a temperature control device, however, when the casing temperature recovered to set the temperature of the category, the temperature control device in power off; Reduced to a value, when the temperature is controlled through increasing the power. Individual cases, the electric heating tube heater data can be divided into copper pipe, carbon steel pipe, stainless steel pipe, individual commonly used stainless steel pipe, some places need explosion-proof heater. Here is to prompt more anti-freezing measures, need to send personnel to observe examine keep insulation installation or the state of insulation materials, if there is damage, leaks or infarction need timely maintenance or replacement, avoid to cause damage. Pressure transmitter winter heat preservation is first to introduce here, in general is a fall in to produce capital, decline in consumption, often need to the length of heat preservation of pressure transmitter.
