More About this Item

1. Sensors provide improved tracking ability and maintain calibration over long periods of time. When replacing a sensor, you do not need to recalibrate. These sensors are suited for use with mercury and oil pumps. Diaphragm type sensor offers quick response—less than 400 milliseconds full-scale. Select a diaphragm type sensor made from 316 stainless steel or silicon based on your application.

2A. Indicators provide precise digital readout of pressure/vacuum. Single-hole installation lets you mount meters into panel cutouts that measure 23/4” (7.0 cm) square or 23/4” (7.0 cm) up to 33/8” (8.6 cm) in diameter (such as those for Hastings, Varian, TeleVac, and other meters). Mounting hardware is included. Indicators include 10-ft (3.0-m) cable to connect sensor and 51/2-ft (1.7-m) power cord for 115 VAC operation. Order optional 20-ft (6.1-m) extension cable—extension won’t affect calibration.

2B. Controllers have all of the features of the indicators plus two independently set SPDT relays for control of high and low limits. Easily adjust set points to any value with front-panel push buttons; connect relay outputs at screw terminals at back of unit.

3. Calibrators let you readjust your meter or controller display quickly and easily to factory specifications (±0.2%). Calibrators provide precise zero and span input values.
