These Pressure Calibrators from KELLER 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
