BIS – Bladder Integrity System - Signal when fluid inside of the accumulator bladder

BIS – Bladder Integrity System - Signal when fluid inside of the accumulator bladder

HYDAC has developed a Bladder Integrity System (BIS).
It detects fluid which has penetrated the bladder and transmits a signal. In addition, the temperature and pressure can be monitored electronically (current loop/HART). The BIS is available together with a bladder accumulator as initial equipment and as retrofit BIS-bladder.

Identifies defective bladder -> Planned repair, reduced downtimes
Pressure and temperature monitoring during operation.

HYDAC ELECTRONIC - Transmitters with HART-Protocol

HYDAC ELECTRONIC - Transmitters with HART-Protocol

In recent years, HYDAC ELECTRONIC have been systematically developing their sensor portfolio.The most recent development is pressure, temperature and flow rate transmitters available with HART protocol.
The transmitters will be available with various approvals. Intrinsically safe device types (ATEX and IECEx).
Ignition protection class "explosion proof" and "flameproof enclosure" accomplished triple certification at the same time (ATEX, IECEx, CSA) and thus, they have become globally applicable.
