FRS4

Providing long-term stability of calibration for laboratories around the world, the FRS4 is a piston gauge pressure calibrator for use in gauge and differential pressure modes.
The precision-manufactured piston assembly produces a differential pressure that is directly related to physical properties.
Highly stable, the instrument gives you confidence in the long-term traceability of your calibrations.
Unlike dead-weight testers, the FRS4 is quick to use and can automatically generate required test pressures.
The instrument is designed to make the calibration of a wide range of pressure gauges and transfer standards easy and fast. 

For increased ease-of-use the control box can be used to set the desired pressure between the test and reference ports (differential mode) or the test port and atmospheric pressure (gauge mode) of the FRS4 instrument.
The controller regulates a flow of air to the FRS4 which establishes a proportional pressure across the piston.
The flow rate is controlled through a combination of the supply pressure and selectable flow restrictors with high and low flow settings, and two bypass settings which can be opened to reduce the air flow in either the high or low range. There is also an exhaust restrictor to reduce the effect of atmospheric pressure change.
All functions of the control box are controlled via RS232 serial communications from a computer or Programmable Logic Controller (PLC), with PC-based software available.
