Profile: Automation Components, Inc. manufactures sensors. Some of our products are carbon monoxide sensors, light level sensors, temperature transmitters, submersible thermistors, enthalpy transmitters and solid/split core sensors. The A/RH series relative humidity transmitter converts a resistance change to a linear 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC output. The transmitter is calibrated using a NIST traceable temperature/humidity chamber. It is used in building automation systems and humidity chambers. The A/CO transmitter monitors carbon monoxide (CO) level in industrial environment, and vehicle exhaust in non-hazardous areas. It uses a wide spectrum, long life electrochemical sensor.
