Description: Pollution and process monitoring system for chlorine gas is manufactured, either in process stream or ambient air to detect PPM level for human/environments safety. The gas detection instruments are available in portable, wall mounting and panel mounting versions with latest user-friendly micro-controller technology with long life electrochemical sensors. These accept input 4-20 mA/3-wire from toxic gas transmitter. The range, resolution, alarm setpoint, alarm control action are programmable by users. The instrument has very high accuracy of 0.25% with software linearisation; easy online field calibration by user from front keys; programmable latch and non-latch facility for relays and LED indication; two independent set points, individual with relay output; and one fault relay for fail safe operation. All three relays have 1 NO/C/NC contacts rated 230 V/5 A. Non-isolated 4 to 20mA retransmission output is available for PLC, DCS and chart recorders, if any. Optional RS-232/RS-485 serial port with Modbus RTU protocol is provided for online PC based data monitoring. The system is very useful for chlorination plants, chlorine plants, nuclear reactors, PVC manufacturing, water treatment, swimming pools, paper mills, acid alkalis and dyes manufacturing, ambient monitoring as well as chlorine cylinder storage area. Chlorine gas monitoring system is manufactured by Ambetronics Engineers, an ISO 9001: 2000 certified company.
