BL1R-BL1H Air or oil reference dead-weight tester - Baumer Bourdon-Haenni - #1

BL1R-BL1H Air or oil reference dead-weight tester

Calibration of pressure transducers, transmitters, pressure gauges and pressure switches. Measuring ranges: BL1R : -0.9 ....120 bar (air)

BL1H : 0.5 .....1200 bar (oil)

Quick connection of devices to be calibrated.

The dead-weight testers BL1R and BL1H are designed for the cali­bration of pressure monitoring systems. They consist of a pressure generator, a cylinder piston unit, including a given S section and a set of weights with an accurate given value m which allow the establishment of the relation P= (m x g)/S and, thus, comply with the units of the International System (SI). As for their design, the dead-weight testers BL1R and BL1H are sturdy, easy to operate and have a excellent long-term stability providing a high metrological property.
