Convert a pressure, level, flow, or temperature process
variable value into the appropriate pneumatic or electrical
value given different types of instruments.
Answer Posted / jadhavamit
You can use pressure switch for pressure indication,
for level u can use DPT
for flow u can use mass flow meter/turbine flow meter/magnetic flow meter/ultrasonic flow meter
and for temperature u can use RTD/Thermocouple.
keep in mind 1 note that every transmitter output is 4-20mAh these is read by every controller and switch output is in form of 1 or 0, means 1 high to its set point and 0 below setpoint.
