The Refrigerant Leak Detector Sensor measures the amount of R404a, R410A and/or R22 present. This sensor measures leaks and spills; it is not intended for critical ppm measurements. Voltage trip levels for R22, R404A and R410A leaks and spills are shown in the table on the next page. The sensor is temperature compensated for an accurate and reliable measurement.
The Water Leak Detector is designed to sense the presence of water and alert a central monitoring system of the potentially destructive situation. Upon water detection, an alarm relay changes state, and a local red LED illuminates. The transmitter can be set for latching alarm or non-latching alarm with normally energized or de-energized operation.
The CO2 Duct Sensor is an accurate and reliable way of incorporating demand controlled ventilation. It measures CO2 in ranges of 0 to 2000, 0 to 5000, 0 to 10000, and 0 to 50000 ppm with a field-selectable output of 0 to 5 or 0 to 10 VDC.
The Carbon Monoxide Transmitter/Sensor offers enhanced electrochemical sensing with outstanding accuracy at low concentrations. The Rough Service unit features a ventilated enclosure and is ideal for parking ramps, equipment rooms and warehouses.
