ETTN range digital atex temperature switches are intended for temperature control for industrial process management. Based on microprocessor technology, the atex temperature switches can be programmed completely on site using code protected keys. The output signal (4...20 mA or 0...10 V) is adjustable between -200°C and 400°C. It is possible to reduce the errors due to thermal resistance of the pipe or thermowell by manually entering the process fluid temperature into the ETTN. The ETTN range comprises three models: with the temperature measurement by a submerged probe, deported probe or by surface contact.
The ATEX RF 95 RS SW is an ATEX Wireless Command Device with certification for use in Zone 1 and Zone 21. The ATEX Wireless Switch has a thermoplastic enclosure and the output signal can be individually configurated at the receiver. The ATEX Command Switch has a data rate of 120 kbps and no power supply, wiring or pipe laying is required. The ATEX Wireless Switch Receiver is multi network capable and is easily programmable.
The Ethernet switches and media converters in the BNT series are used as stationary devices in potentially explosive atmospheres of device groups I and II.
They are used to transfer optical or electronic data signals up to a maximum bandwidth of 2 Gbit/s.
They are available in two different models, with aluminium housing for use in ATEX Zone 1 and 21 and the stainless steel housing for use in the ATEX M2 area.
