Sourcing Pressure

W WARNING

 

The calibrator provides a source pressure display function that requires the use of an external pressure hand pump. Use this function to calibrate instruments that require a pressure source or differential pressure measurement. See Figure 31 for information about that application.

Pressure modules are available in gage or differential types, depending on range. (See “Accessories” near the front of this manual.) Gage pressure modules have one pressure fitting and measure the process pressure with respect to atmospheric pressure. Differential pressure modules have two pressure fittings and measure the difference between the pressure applied to the high fitting and the pressure applied to the low fitting. If the low fitting is left open, the pressure module acts as a gage unit.

To use the source pressure display, see Figure 17 and proceed as follows:

TO AVOID A VIOLENT RELEASE OF PRESSURE IN A PRESSURIZED SYSTEM, SHUT OFF THE VALVE AND SLOWLY BLEED OFF THE PRESSURE BEFORE YOU ATTACH THE PRESSURE MODULE TO THE PRESSURE LINE.

CAUTION

To avoid mechanically damaging the pressure module, never apply more than 10 ft.-lbs. of torque between the pressure module fittings or between the fittings and the body of the module. Always apply appropriate torque between the pressure module fitting and connecting fittings or adapters.

To avoid damaging the pressure module from overpressure, never apply pressure above the rated maximum printed on the pressure module.
