描述
满足高要求
IS-3 型压力变送器特别适合在危险区域中使用。这款压力变送器专为高的工业要求而设计，符合 ATEX、IECEx、和***，并达到 SIL 等级要求。
IS-3 型压力变送器测量量程广，高可达 600 MPa，能满足从常规机械制造到 LDPE 生产中高压应用场合的需求。
设计
所有接液部件均由不锈钢制成，传感器通过焊接与螺纹部分连接在一起。接液材质部分不使用任何密封部件，因此可用于几乎所有介质。外壳也采用不锈钢，坚固耐用，低 IP 防护等级为 IP 65。另外也提供 IP68 等级的型号。
Description
For the highest demands
The pressure transmitters of the IS-3 series have been
specifically designed for the highest industrial requirements
in hazardous areas and feature the common approvals, such
as ATEX, IECEx, and , as well as a SIL rating per
IEC 61508 / IEC 61511 for use in the process industry.
The model IS-3 pressure transmitter is available with
measuring ranges up to 6,000 bar and is suitable for
applications ranging from general machine building to
high-pressure applications.
Design
All wetted parts are manufactured from stainless steel and
are fully welded. Internal sealing elements are completely
avoided, so that the unit can be used with almost all media.
The robust case is also made of stainless steel and provides
a minimum ingress protection of IP65. IP68 versions are also
available.
The process connections with flush diaphragm are
particularly suitable for the measurement of viscous and
contaminated media and ensure trouble-free pressure
measurement at all times.
The optional field case of the model IS-3 enables operation
in extreme environmental conditions and is resistant to
acids, bases, oils and solvents. Via the field case connection
integrated into the case's head, the electrical cabling can be
installed quickly and easily.
Voltage supply
It is recommended that the intrinsically safe variants of the
IS-3 series are powered via a suitable repeater power supply.
An ideal voltage supply is offered by the intrinsically safe
repeater power supply model IS Barrier, see “Accessories”.
