Flexibility to fit your application needs

··

· Compatible for Marine Applicaions

Integral or Remote mounting Sensor.

Interfaces with Industry Standard Transmitters. ·

·

· Ingress Protection IP-65

Applied Field proven gas Monitor/Transmitters continuously monitors for dangerous

concentrations of gases. The linearize 4-20 mA transmission can interface directly with any

receiving instrument starting from indicators, controllers to large control systems.

Provision for directly connection of buzzer/Hooter for Alarm through Relay.

The standard system consist of a compact electronic module housed in a Weatherproof or

explosion proof Metallic or Polyester box with an application specific sensor. This state

of the art transmitter is carefully designed with and manufactured with Industrial grade

Components for reliability accuracy and long life. It is certified for use in hazardous

areas Class 1, Division 1, Group B, C & D. (IIA, IIB or IIC), IP 65 apart from being

available in weatherproof Enclosure Transmitters are equipped with micro controller and

are heavily featured with self diagnostics, Auto calibration (in case of toxic, Oxygen,

combustible gases only) through embedded Software, can be done at site. RS 232/485 output

with baud rates of 2400 bps is available as an options.
