LAUDA Announces Explosion-Proof Command Ex i Remote Control

From the third quarter of 2010, LAUDA will offer an explosion-proof version of the Command remote control. The intrinsically safe design of the control panel is authorised for explosion protection II 2G EEx ia IIC T4. The modular nature of LAUDA thermostats means that this control unit, Command, can be used with the LAUDA Integral XT, Proline Kryomats and Proline devices.

The thermostats themselves are set up outside of the ex-zone. In addition to the actual control panel, two barrier boxes are also supplied, which are connected between the device and the control panel in order to ensure that the electrical currents are limited. The barrier boxes connected to the thermostat are connected to the Command and optionally to a sensor, which can be used as an external temperature gauge. Possible sensors would be a Pt100 resistance thermometer or a 4-20 mA temperature sensor.
