ACI A/AN Series A/CP Series A/3K Series A/1.8K Series A/20K Series Temperature Sensor

Temperature Sensor
A/AN Series A/CP Series A/3K Series A/1.8K Series A/20K Series

The A/10K-AN (Type III), A/10K-CP (Type II), A/3K, A/1.8K and A/20K Series temperature sensors are thermistor type sensors. These sensors provide a predictable output over a specified temperature range to meet each manufacturer’s required input values. (See web page for complete curve chart specifications) These units are offered in Room, Room with Set Point, Room with Override, Room with Setpoint and Override, and Room w/ Setpoint, Override, and RJ11 Jack, Stainless Steel Duct and Duct without Box, Immersion, Stainless Plate, Raw, Bendable Copper and Stainless Steel Rigid Averaging, Strap-On, Bullet Probe, Button Sensor, and Outdoor Air Configurations. All ACI Room sensors may be ordered with an optional setpoint (see chart on the following page), override, or with a 4 pin RJ11 or 6 pin RJ12 communication jack with terminal blocks, for remote programming. These units are also available with a 1/8 RS232 Stereo Jack.

• Offer high accuracy and interchangeability over a wide temperature range.
• Higher resistance output relative to Platinum RTD’s
• Non-polarity sensitive Applications
