Temperature Sensor Module - ACM1016 - AirCare Automation - #1

Text version of the page

Temperature Sensor Module Overview AirCare’s ACM1016H Temperature Sensor Module provides a 0-5 volt output relative to a temperature at the sensor surface. The ACM1016H, along with the AirCare VariPhase™ (ACV1xxx) can provide either closed-loop, regulated temperature for fan-controlled systems or open loop primary set point control. Once configured, the system will automatically adjust fan speed to in response to changing temperatures. The ACM1016H may be used only in air or nonconductive gas environments; Liquids or corrosive gases will damage the unit. Product Description The ACM1016H uses a thermistor bridge control circuit to provide a 0-5 volt analog signal to the controller based upon the measured temperature. The unit adjusts the dc output voltage around the mid-point setting of the sensor. The ACM1016H provides small size, ruggedness and excellent stability with reduced drift. The ACM1016H can be powered from the 12V output of AirCare VariPhase or from any 12Vdc source. The ACM1016H range can be customized from 0°C to 50°C with the pre-mounted thermistor on the PCB. Higher temperatures can be accommodated using an off-board thermistor. The ACM1016H provides linear control over +/- 50% of the mid-point temperature, which is designed to provide 2.5 volts output. A 1 degree change in temperature equates to 50mV change to the output of the ACM1016H. Custom ranges can also be accommodated. Specification

Typical 1% change in temperature = <2% change in full range dc voltage (output) Installation The ACM1016H is provided with a mounting bracket to allow easy placement. A three wire cable is provided that will connect to the terminal strip and the controller. The unit can also be provided in a protected casing for greater board protection. Place the ACM1016H in a stable environment for best results. The ACM1016H dc output can be used to either set the controller speed (analog control) or be used for closed loop control (feedback control signal) of temperature using an external setting. The ACM1016H is not linear over the full range (0-100%); It is quite linear over mid-point range. The curve below shows the setting output (on a 0-100% scale) vs. Temperature. Probe Temp.
