To calculate temperature, why we multiply 25 with mV?
Answer Posted / carl_ellis
Apparently, your temperature signal is linear across a mV
range, coming from some type of temperature transmitter,
and the mV value represents temperature/25.
If your source is a raw thermocouple signal, then
multiplying by 25 does NOT result in a true temperature
value because
- cold junction compensation has not be applied
- thermocouples are not linear
Temperature transmitters perform both of those tasks, cold
junction compensation and linearization of the output
signal.

Why does a pressure gauge installed on reactor, doesn't have any vent line below to release the pressure? Is it any kind of designing mistake or it actually does not require any vent line? And if it does not require any vent line below it then how we are gonna release the pressure built inside the pressure gauge?
