Platinum Temperature Sensors
ACI/100 Series
ACI/1000 Series


Product Description:

The ACI/100 And ACI/1000 Series temperature sensors incorporate a Class A thin film platinum RTD sensor which conforms to DIN-IEC-751 platinum RTD standards.

These Sensors are available in either two or three wire configurations incorporating high accuracy and interchangeability throughout a wide temperature range.

These units are offered in Room, Room with Set Point, Room with Override, Room with Setpoint and Override, and Room with Setpoint, Override, and RJ11 Jack; Duct, Duct without Box, Immersion, Stainless Plate, Raw, Averaging, Strap-On, Bullet Probe, and Outside Air Configurations.

Setpoint options include a linear 400 Ohm, 1K, 2K, 5K, 10K, 20K, or 100K potentiometer. An optional series resistor allows for any offset of the setpoint potentiometer. These may be either Direct or Reverse Acting.

Indication stickers for setpoint include Cool|Warm, 55 to 85, and 10 to 30°C. Others are available upon request.

Override options include a N/O switch in parallel with the sensor or a separate 2 pole terminal block for tenant override.

All ACI sensors also come with optional 4 or 6 pin RJ11 communication jacks with terminal blocks for remote programming.
