The SIM922A Diode Monitor and the SIM923A RTD Monitor continuously read a single sensor and provide both digital and analog outputs. Based on the modular SIM platform, they provide high performance capability in a small footprint..sim922a二极管的监器和sim923a RTD续监测单传感器提供数字和模拟出。基于模块化的仿真平台他们在一个小体积提供性的。SIM922A.sim922a。The SIM922A has a programmable, precision 10 µA current source to provide sensor excitation. Results can be displayed in either kelvins or volts..有一个可编程的sim922aµ精度10电流源提供传感器激励。结果可以是绝对或电压显示。SIM923A.sim923a。The SIM923A has selectable 10 µA and 1 mA current sources to provide sensor excitation. Sensor resistance is determined ratiometrically with a half-bridge circuit consisting of the sensor and an internal reference resistor. The current to the sensor can be reversed by the user to test for any offset. Measurement results can be displayed in either kelvins or ohms.具有可择的10个和sim923aµ1毫安的电流源来提供传感器激励。传感器的电与一个半桥电组成的传感器和一个内参电的比例确定。对传感器的电流可以用户的任何偏移测。测结果可以显示K或欧姆。
