HNL's proven micro-controller based Field Transmitters are designed to provide unmatched output and accurate results with high durability. These transmitters are gas-specific transmitters configured with negligible cross-interference. These continuously monitor different hazardous concentrations of gases and interface directly with different receiving instrument / system. The standard transmitters are designed with a solid electronic module enclosed with a weather or explosion proof polyester or metallic box. They also come with an application specific sensor, relay output and easy sensor replacement features. In addition, they are also available with explosion proof & IP65, IP55 rating, 2 or 3 wire output having smart sensor interface, HART / MODBUS (RS485). They are well-equipped with micro-controller and optional self diagnostic as well as auto-calibration functions having embedded software.
