For the highest demands
The pressure transmitters of the IS-3 series are ideally suited to applications in hazardous areas. These pressure transmitters have been specifically designed for the highest industrial requirements and feature the ATEX, IECEx and EAC approvals as well as a SIL rating.

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 in the LDPE production.

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 nearly all media. The robust case is also made of stainless steel and provides a minimum ingress protection of IP 65. IP 68 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 isolated barrier. An ideal voltage supply is offered by the model IS Barrier isolated barrier, see “Accessories”.
