Dual-channel temperature controllers

Staff -- Control Engineering, 8/1/2006

Model 325 dual-channel temperature controller from Lake Shore Cryotronics supports nearly any diode, RTD, or thermocouple temperature sensor to measure and control temperatures from 1.4 to more than 1,500 K. Sensor inputs are factory configured with two diode/RTD inputs; up to two thermocouple inputs can be requested at the time of order. Two PID control loops with maximum heater outputs of 25 and 2 W drive either a 50 or 25 V load for optimal cryocooler control flexibility. Control Loop 2 heater output is a single-range, variable dc voltage source. When not used for temperature control, Loop 2 can be used as a manually controlled 0 to 10 V source. IEEE-4888 and serial interfaces are included. www.lakeshore.com/325.html Lake Shore Cryotronics Inc.
