Transmitter sensor operating temp
Transmitter sensor operating temp
(OP)
Hi
In some pressure transmitter manuals ..its written that minimum temperature for its sensors is for example is - 40 C.. but they are actually installed in a line of - 160 C (Liquified gas process) and it gives correct reading .. my question is how is this possible ?

The typical method of isolating the transmitter from the liquid is to mount the transmitter above the process and use the heat of an impulse line to vaporize the liquid to maintain a gas pocket in the impulse line.
