Frequently Asked Questions (FAQs)
1. What are the 4 types of pressure transmitter?
The 4 types of pressure transmitters are capacitive pressure transmitter, thin-film resistive pressure transmitter, optical pressure sensor, and hydrostatic pressure transmitter. Each type utilizes different technologies to measure and transmit pressure data.
2. How does a pressure transmitter work?
A pressure transmitter works by transmitting the pressure of the medium to a central measuring diaphragm. The pressure difference between the diaphragm and the membrane causes the membrane to deform. This deformation is then measured to determine the amount of pressure difference.
3. Where should a pressure transmitter be installed?
For systems with straight duct runouts, it is recommended to install the pressure transmitter in the main trunk, at least two-thirds of the way down the line. This ensures that the most remote VAV boxes on the system receive the necessary pressure when the system is maintained at setpoint.
4. Why is 4-20mA used instead of 0-20mA?
The use of 4-20mA instead of 0-20mA is primarily due to the elevated 'zero' value. This allows for powering the field device on the same two wires used for signal transmission. The lower limit of 4mA ensures that the loop current never falls to zero, enabling loop-powered operation and a two-wire circuit.
5. Why is 4-20mA used instead of 0-10V?
The use of 4-20mA instead of 0-10V is advantageous because the bottom span of 4mA expresses a minimum signal value even in the case of a broken wire. Additionally, 4-20mA is considered an intrinsically safe signal in most locations. The use of loop current rather than voltage allows for loop-powered operation and simplifies wiring.
