ACI/334 Semiconductor Type Temperature Sensors

Semiconductor Type Temperature Sensors
ACI/334 Series

Product Description:
The ACI/334 Series semiconductor type temperature sensors provide accurate temperature measurement that is linear and proportional to Degrees Fahrenheit.
The ACI/334 sensor provides a 2.406 to 3.869 VDC or a 240uA to 386uA output throughout the temperature range of -13 to 212oF.
These units are offered in Room, Room with Setpoint, Room with Override, Room with Setpoint and Override, Duct, Immersion, Stainless Plate, Raw, Strap-On, and Outside Air configurations.
Setpoint options include a linear 400 Ohm, 1K, 2K, 5K, 10K, 20K, and 100K slide pot and any offset resistor in series with the potentiometer.
These may be ordered as either Direct or Reverse Acting.
Override options include a normally switch in parallel with the sensor or a separate two-pole terminal block for tenant override.
Custom configurations are available upon request.
