ZTC-100 series intelligent liquid nitrogen level monitoring instrument is designed to measure the level and temperature of liquid nitrogen container. It uses micro controller technology and platinum RTD to measure the temperature with digital display. It has low-level alarm, over-temperature alarm, sensor failure alarm to monitor the temperature and level of liquid nitrogen containers. It also could be connected with solenoid valves to fill liquid nitrogen automatically. RS485 signal and standard current signal (4 ~ 20mA) output function are optional for connection.
