Description Specifications Literature Description The Series 65-120 Portable Pneumatic Calibrator is a pressure-vacuum test stand wholly contained in a carrying case. The front panel accommodates the precision pressure gauge, all pressure connections, two air-regulator controls, and a selector valve. With the selector valve, three different test pressures can be applied individually to the gauge. A fourth selector setting vents the gauge to atmosphere. The precision pressure gauge has a Ni-Span C, capsule-type pressure element which gives excellent temperature stability and speed of response. An almost frictionless mechanical linkage amplifies capsule movement and transmits it to the pointer. Although highly sensitive and accurate, the mechanism is built to withstand the handling normally associated with on-site calibration of pneumatic instrumentation. A filter on the air supply keeps oil and moisture out. Two regulators apply known pressures to the devices under test. The connection block has 1/8-inch female-pipe-threaded connections. Small gauges can be threaded directly into the block; or as with larger instruments, connected by flexible tubing.
