FST500-304 Liquid - level Display Controller

Production introduction

FST Display Controller is based on microprocessor, with the function of calibration, digital filtering, which can reduce the error of sensor and transmitter, improve the testing and measuring accuracy. The Alarm output up to 8 sets. It has the delayed alarm function which can prevent false alarms caused by the interference, etc.Display mode of controller: LED, LCD, beams. Digital circuit carefully designed the working condition of RFI & EMI resistance, and the surge voltage. It has the characteristics of strong RFI & EMI resistance, lighting & polarity protection, meeting IEC, CE(EMC) requiement. The products is fully conpatible with FST pressure sensors, temperature sensors, displacement sensors and liquid-level sensors.
