Danfoss introduces 'Intrinsically Safe' Pressure Transmitters.
Danfoss has expanded its range of market leading
pressure and temperature measurement components
with a new range of four intrinsically safe pressure
transmitters for use in areas with potentially explosive
gases or steam.
Designed to comply with the strictest safety, robustness and
measuring reliability demands in potentially explosive environments,
the four new pressure transmitter types comprise: MBS 4201,
MBS 4251, MBS 4701 and MBS 4751. The transmitters all
have the EX-approval EEX ia IIC T6 in accordance with the
ATEX directive and can be applied in zone 0, zone 1 and
zone 2, making them already compliant with the new directive
that came into effect in July 2003.
All are made from stainless steel, have an output signal of
4-20mA, deliver measuring ranges from 0-1 bar up to
0-600 bar in both absolute and relative versions and can
be specified with a wide range selection of pressure
connections. Types 4201 and MBS 4251 transmitters have
an accuracy of +/-1%, are available with DIN 43650 plug,
DIN 72585 bayonet plug or with blue Ex-cable and can be
supplied with a protection rating of IP 65 IP 67 or IP 69.
Types MBS 4071 and MBS 4751 transmitters have an
accuracy of +/-0.5% FS, are available with DIN 43650 plug
(IP 65), and are equipped with zero point and span adjustment.
When used in applications involving cavitation, liquid hammer
and pressure peaks, types MBS 4251 and MBS 4751 are
equipped with a pulse-snubber in the pressure connection
that uniquely protects the transmitter against the violent pressure
and shock impact. This may occur in applications with sudden
changes in the liquid flow (ie when starting or stopping a pump
or when opening or closing a valve).
