Vacuum Loss Detector VLD

The VLD Vacuum Loss Detector monitors high vacuum insulated applications. The monitoring is permanent and reliable (24/7).

The VLD is a two-part monitoring system. It consists of an explosion-proof high vacuum sensor and an associated indicating unit (single version) that triggers an optical and audible alarm. The alarm is given at the earliest possible moment.

The sensor is explosion-proof through Ex-d or Ex-i (pressure proof encapsulation or intrinsically safe).

The indicating unit (available in a single or a double version) is equipped with dry relay contacts for alarm-forwarding. It comes in a weather-proof stainless-steel housing with IP 66.

For the monitoring of two separate interstitial spaces/vacuum insulations, two sensors and the double indicating unit are used.

Design of connections, e. g. flanges, according to customer requirements.

Pre-alarm and main alarm thresholds are programmed according to customer's specification.

Key features

Continuous monitoring of the vacuum insulation even during intermittent operation.

Immediate and constant information on the functionality of the vacuum insulation.

Direct and early alarm signalling in the event of vacuum loss, allowing knowledge of safety risk and thus time for countermeasures/safety measures.

Vital safety and health protection for employees at the plant.

Minimization of downtimes and its consequential costs due to vacuum insulation loss.
