Description
The model E-10 and E-11 ameproof pressure transmitters
have been designed specically for the high demands of
industrial oil and gas applications.
These pressure transmitters can be delivered with various
analogue signals from 4 ... 20 mA to a low-power version with
DC 1 ... 5 V.
They feature an exceptionally high resistance to vibration,
pressure spikes and moisture ingress. Furthermore,
these pressure transmitters full IP67 (NEMA 4x) ingress
protection.
On each individual instrument a comprehensive quality
control and calibration is performed, so that an accuracy
of ≤ 0.5 % can be ensured. Temperature compensation
guarantees accuracy and long-term stability, even with strong
uctuations in the ambient temperature.
The models E-10 and E-11 are suitable for sour gas
applications and feature particularly high resistance against
sulphide stress cracking when in contact with sulphurous
gases.
The pressure transmitters are approved as “explosionproof”
for class I, II, III, div. 1 hazardous areas to FM and CSA as
well as “ameproof” for II 2G Ex db IIC T6...T1 Gb to ATEX
and IECEx.
