(9) Devar alarms are designed to accurately monitor process trip-points from current, millivolt, DC volts and thermocouple signals. These alarm points can be easily set in percent of signal or directly in engineering units. The units will constantly monitor the set point against the actual signal and switch a 10 amp SPDT relay when the set point is exceeded. Alarms are available in wall mount, panel mount, track or DIN rail mount, AC/DC line voltage powered or loop powered versions.
DEVAR calibrators are light weight, easy to use, highly accurate portable calibration devices. They are hand held, battery operated devices that can be used to simulate current outputs which can drive loads up to 1000 Ohms. DEVAR calibrators are also available to measure/simulate thermocouple, RTD, milliamp, pH and pneumatic signals.
