Volume Controllers

The Ralston Instruments Volume Controller is an excellent solution for a wide range of Pressure Control Applications.

 

Differential Pressure transmitter Calibration – Use the Volume Controller to hit pressure test points quickly and accurately. It can be used without nitrogen to control pressure for calibrating the differential pressure side of a pressure transmitter up to 400 inH2O / 1000 mbar. With compressed nitrogen applied it can be used to control pressure for calibrating the static side of a pressure transmitter to 3000 psi / 200 bar.

Analog pressure gauge calibration – When used in conjunction a digital test gauge and a 2 or 4 port benchtop manifold it can be used to calibrate 2 or 4 of the same range pressure gauges at the same time. This works much quicker and more efficiently than a deadweight tester for calibrating analog pressure gauges. This makes an excellent choice for a laboratory to calibrate pressure gauges in a wide range of pressures.

Vacuum pressure gauge or transmitter calibration – Connect the Volume Controller in line with a mechanical vacuum pump. Pull a vacuum on the inlet side of the Volume controller and control vacuum to precise test points better than with virtually any other device.

Float Pneumatic Piston Gauges – In high precision pressure calibration the Volume Controller can provide a precise pressure to float a piston gauge so that the piston gauge can deliver accurate pressure
