Redundant compact monitor for SIL 2 / PL-d Machine protection according to EN 13849

The fully redundant SIL 2 / PL-d Cat 3 vibration monitor from PCH Engineering are suitable for enhanced protection according to EN 13849. Use them to permanently monitor critical and dangerous machinery.

You are probably aware that, for safety-related parts of a control system, Functional Safety Guidelines state the need for redundancy and diagnostics in the structure.

When full redundancy is legally required for your machinery, what you need is a redundant vibration monitor with two fully separated, parallel measuring channels with individual vibration sensors.

That is what you get with the redundant vibration monitors from PCH Engineering. The built-in 1002 D architecture will leave the alarm function fully operational even if one of the two parallel measuring channels is faulty.

Price-Attractive Alternative

The PCH solution is an integrated solution with two individual vibration monitors in one housing. This means that you no longer need to place two individual vibration monitors next to each other – one is enough.

In other words, you get the same level of protection as in a traditional solution, but at a lower price.

Easy Installation

With the redundant vibration monitors from PCH, installation is as simple as in the PCH Compact Range: Only one M12 mounting stud is needed.

Our experienced consultants are happy to help you find the right vibration monitoring solution for your machinery.

Redundant SIL 2 Vibration Monitor

PCH 1290 Redundant Vibration Monitor

The redundant SIL 2 vibration monitor PCH 1290 consists of two independent vibration monitors built into the same compact housing.

With this vibration monitor you get two 4-20 mA outputs and redundant alarm relays for full protection in accordance with Functional Safety EN13849, PL-d.

This special design places PCH 1290 in the Category 3 with an architecture 1002 D.

PCH 1290 features:

Rated according to EN 13849, PL-d, Cat 3
Measuring parameter: velocity mm/s or acceleration m/s²
Typical frequency range: 1-30/10/300 or 10 to 1000 Hz
2 alarm levels with individual delay times and redundant alarm relays
Redundant analogue DC outputs RMS 4-20 mA, proportional to 0-100 %
Measuring range selectable: 10/20/50/100 mm/s or 10/20/50/100 m/s²
Self-test function can be activated externally
Safety level SIL 2, GOST-R certificate and UL approved
