How to adjust 20 psi air supply to a transmitter?

The general stages of adjusting a 20 psi (pounds per square inch) air supply to a transmitter are as follows:


Determine the pressure adjustment mechanism: A pressure regulator or control valve are common pressure adjustment mechanisms found in transmitters. Find this device in the air supply pipe or on the transmitter.

Assemble the required equipment: Depending on the type of adjustment mechanism available, you might need a screwdriver.

Establish the desired pressure: Discover the precise pressure that your transmitter needs. Before continuing, make sure you have this value available.

Switch off the air supply: In order to avoid unintentional pressure changes while making adjustments, be sure to switch off the air supply to the transmitter.

Access the adjustment mechanism: A pressure regulator adjustment mechanism may feature a knob or screw. There might be an adjustable screw or another comparable device for a control valve.

Adjust the knobs, screw: Turn the adjustment knob, screw, or other similar mechanism slowly to gradually increase or reduce the pressure. Make only little adjustments at first, then wait for the pressure to stabilize before continuing.

Monitor the gauge pressure: Utilize a pressure gauge attached to the transmitter or, if one is available, the transmitter’s internal pressure display to keep track of the pressure while adjusting. The pressure should be adjusted until it is at the correct level.

Adjust the lock: Once the desired pressure has been attained, see if the adjustment mechanism contains a locking mechanism (such as a locknut or set screw). Secure the mechanism if it is accessible to stop future unintentional alterations.

Switch on the air supply: Turn on the air supply after locking the adjustment mechanism, then check to see if the transmitter responds to pressure changes within the predicted range. To make sure the transmitter is operating properly, keep an eye on its performance.

To ensure appropriate adjustment and prevent any damage, refer to the instructions or seek advice from a professional knowledgeable with the particular transmitter model.
