Multiple Point Fixed

The system includes:

Two INTERSCAN electrochemical voltametric sensors with dedicated pneumatics
Two dedicated digital display/controllers. From here, two alarm levels, independently adjustable for each sensor, are set via easy push button operation.
Alarm relay contacts for each alarm setpoint, at each sample channel
4-20 mA output for each sample channel
Strobe (visual) and piezoelectric (audible) alarm signals, providing an indication in the event that either channel goes into alarm
Two remote sample point boxes, each provided with the appropriate end-of-line particulate filter, and 50 feet (15.2 meters) of tubing

Dedicated sensor, sample pump, and stainless steel rotameter for each point
All control and display functions at easy-to-use operator interface
User adjustable low and high alarm set points, activating dedicated relays for each monitoring channel
Stackable tower lights for low, high, and fault alarms, and piezoelectric horn for high alarm, common to all channels
Alarm event and time of occurrence tracking, plus last time calibrated tracking, specific for each sensor
Vacuum fault detection and fault display, for all sample pumps
4-20 mA analog output, for each channel
