How to Calibrate Pressure Transducer Using HART
Communicator?

• Calibration Services in Singapore is an vital
  step that allows gadgets to provide correct
  measurements. Calibrating a strain transducer the
  usage of HART (Highway Addressable Remote
  Transducer) communicator is one of the simplest
  and maximum dependable approaches to calibrate
  strain transducers.
• To calibrate the strain transducer, you ought to
  first want a energy supply to energise the
  transducer. Connect the ammeter to the wonderful
  line from the transducer.

3

• Connect a strain supply to the HP line of the
  strain transducer. Using a hand pump with a
  analyzing scale is the excellent option.
• Leave the LP facet vented to the atmosphere.
• Connect The HART communicator to the strain
  transmitter. Take measurements at 0 strain and
  degree at small increments. If the transmitter
  suggests an error, then calibrate the transmitter
  through adjusting the Span and Zero withinside
  the Hart Communicator.

How to Calibrate the Absolute Pressure
Transducer?

• Absolute strain transducers assist us to degree
  the strain that isn't always stricken by the
  atmospheric strain. Hence, the calibration of an
  absolute strain transducer is lots one-of-a-kind
  from different kinds of strain transducers.
• In Calibration Laboratory Singapore, The first
  step is to depressurize the complete device
  through beginning the discharge valve after
  ultimate the isolation valves.
• Attach the strain calibrator hose to the NPT
  strain port. Connect the Red lead and the Black
  lead from the strain calibrator to the wonderful
  and poor check terminals of the strain sensor.

5

• Switch at the strain calibrator and open the vent
  through turning it counterclockwise. Press the 0
  button after which near the vent.
• Select PSI through clicking the Units button and
  press the 0 button. Close the bleed valve and
  pass the strain vacuum values to .
• Create a strain of three psi the usage of the
  hand pump. Maintain the strain and notice down
  the values for mA and psi. Increase the strain at
  ordinary durations and notice down the values.
  See if the mA values correspond to the psi values
  as in step with the manufacturers
  specifications. If they do now no longer match,
  use the manufactures course to manually set the
  values.

How to Calibrate a Vacuum Pressure Transducer?

• A vacuum strain transducer, additionally called
  an absolute strain transducer, measures the
  strain unaffected through the atmospheric strain.
  To calibrate vacuum strain transducer, use the
  subsequent steps.
• Close the isolation valves and open the discharge
  valve. This will depressurize the entire device.
  Connect the calibrator hose to the NPT strain
  port. Connect the crimson result in the wonderful
  check terminal and the black result in the poor
  check terminal.
• Switch ON the strain calibrator. Turn the vent in
  a counterclockwise course to vent the device. Set
  the fee to 0 through clicking Zero and near the
  vent.

7

• Select the dimension unit to PSI through clicking
  the Units button. Click 0 to reset the values.
• Close the bleed valve and set the strain vacuum
  fee to .
• Use the hand pump to create a strain of three
  psi. Note down the psi and mA readings. Now boom
  the strain and notice down the values again.
  Follow this technique to get more than one
  readings. Now, evaluate the mA fee you wrote
  right all the way down to the manufactures
  specification for a given psi. If the values
  dont coincide, calibrate the vacuum strain
  transducer the usage of the manual furnished
  through the manufacturer
