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 I and zone 2,
making them already compliant with the new directive that comes into
effect in July 2003.
All are made from stainless steel, have an output signal of 4-2OmA,
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 +1-1%,
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 +1-0.5% 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).
