The large display with 17 mm digit height enables employees to read the gas concentration from distances never seen before. In applications where the display of the transmitter can not be read because of its mounting position, a Remote Display is easily connected to a digital bus interface.

A linear output signal is transmitted by means of a cost effective 2 wire cable to the controller in a control room. Here the gas concentration is displayed and alarms are switched on to warn employees, security or the fire brigade.
