Add to compare

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.

Applications

  • Bunkering
  • Offshore-bunkering
  • Dispensing
  • Storage

Use cases

  • In cooperation with BRUGG: Alternoil, LNG project and several petrol stations.
