March 8, 2012 - Sentry Calibrator takes a 2 or 3 wire 4-20mA sensor output and applies a two point correction factor to provide an isolated two wire 4-20mA output. The Sentry Calibrator can compensate for older sensors that have drifted out of tolerance, provide enhanced accuracy for less expensive sensors, or can be used to perform routine calibration in circuit. The Sentry Calibrator can be programmed via a USB cable from a laptop or PC and is available as a wall mount or DIN rail mount package. Price is $75.
