Test & Calibration \ Calibrators and Test Instruments for Temperature and Pressure \ Pressure Calibrators

Product details

These Pressure Calibrators are very precise calibration instruments for the calibration of pressure transmitters, pressure switches and pressure gauges.

The Low- and Medium ranges are pneumatic, and the High ranges are hydraulic. The portable housing incorporates the pressure generating pump, a high precision reference sensor and the measuring electronics.

The transmitter under test is connected to the pressure port of the calibrator and the signal is read out directly on the display. Various internal functions and performance features assist the user in many different measuring tasks. In addition, the serial interface allows the transfer of the measured data onto a PC for further processing. The calibrator, including accessories, is supplied with a robust carrying case and is ideal for outdoor, on-site use.

To meet differing requirements, two basic versions of the calibrator are offered:

Full-Version
The Full-Version of the calibrator is a complete, self-contained transmitter testing unit. With internal supplies for the transmitter and the calibrator itself, the self-contained instrument is always ready for use. For a variety of measuring and testing tasks, a wide selection of software functions are incorporated:

• MANO
  displays the pressure and the maximum and minimum pressures.
• MANO (with transmitter connected)
  displays the pressure, the transmitter signal and the temperature.
• HOLD
  freezes the actual measured values on the display.
• TARA
  sets the pressure display to zero (volatile).
• UNIT
  scales the display into different pressure units (bar, PSI, kPa...).
• LEAK
  determines the pressure decrease (or increase) over a pre-set time period.
• REC
  records the measured values (the number of values and the interval are programmable).
• RESO
  reduces or increases the resolution.
• ZERO
  sets the pressure display to zero (permanently).
• PST
  records the switching points of pressure switches.
• LIN
  calculates the linearity error of the test transmitter.

Standard-Version
The Standard-Version is limited to the essential features for precision pressure generation only. For this simplified operation, this version does not include the integral transmitter supply, nor the display of the transmitter signal. Thus it does not incorporate the PST and LIN functions.
