Nickel Temperature Sensors
ACI/1K-Nickel



Product Description:

The ACI/1K-Nickel Series temperature sensors incorporate a wire wound RTD sensor which provides a predictable output over a specified temperature range of -50 to 275°F.

These Sensors are available in a two wire configuration 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, Strap-On, Bullet Probe, Averaging, 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. The slidepot action may be either Direct or Reverse Acting.

Indication stickers for the 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.
