Used with any controller capable of processing a 4-20 mA or 2-10 Vdc signal.


The Carbon Dioxide (CO₂) Sensors offer a fixed 0-2000ppm and fixed 0-10Vdc output. No adjustments are necessary. Like the C7232 sensors, these are for use in determining ventilation necessity with HVAC controllers.

The sensor measures the CO₂ concentration in the ventilated space or duct...


The C7750A is a direct wired temperature sensor that is used to sense discharge or return air in a duct that may be controlled by an Excel 10 Controller. The C7750A Sensor consists of a temperature sensitive 20K ohm thermistor that is connected on a circuit board to two linearizing resistors in...


Direct wired temperature sensor used to sense discharge or return air temperature in a duct controlled by an Excel 10 Series 2000 Controller.


The C7772 series of wallplate Temperature Sensors are designed to be used with the Excel 5000 family and other Honeywell controllers. The C7772 sensors provide a resistive output signal proportional to sensed room or space temperature. The C7772 is well suited for low profile wall mounted...


The C7915 Flame Sensor includes a lead sulfide photocell that is sensitive to the infrared radiation emitted by the combustion of fuels such as natural gas, oil, and coal.


The Solid State Ultraviolet Flame Detectors detect the ultraviolet radiation emitted by combustion flames. The flame detectors are used with Honeywell flame safeguard controls to provide flame supervision for gas, oil, or combination gas-oil burners.


A self-checking flame detector using a solid state UV sensor to detect ultraviolet radiation in flames for supervision of gas, oil or combination gas-oil burners.


The C7962B Visible Light Flame Detector detects the visible light emitted by fuel oil combustion flames. The C7962B Detector is used with Honeywell Flame Safeguard controls to provide fuel oil flame supervision in commercial and industrial burners


All of these sensors have a solid-state output with an adjustable or fixed trip point (setpoint). These current switches should be used in applications in which a “Go/No Go” current switch is required. The current switches can be used to monitor devices with a maximum continuous operating...
