Vacuum Leakage Sensing Systems
VLS Series – The Latest in Solid State Vacuum Leakage Detection – Made in the USA! Made in the USA!

VLS system now comes equipped with both a rechargeable on board battery (OBB) in addition to the existing 9v battery back up (BBU) for added security and convenience!

The VLS monitors vacuum level of various systems. If the pre-set percentage of vacuum is lost during a lift, a loud horn sounds and a red light flashes to warn the operator. (NOTE: The alarm will not activate during release mode, or from a sudden catastrophic loss of vacuum.)

ALL ANVER Vacuum Lifters, Tilters, and special vacuum lifting machinery, can be equipped with the new VLS Vacuum Leakage Sensor by means of connecting the vacuum source to be monitored with appropriate ¼” flexible tubing, (Part No. PC-T14, clear), to the ¼” push-to-connect vacuum input fitting.


  • Advanced Solid State Circuitry with state-of-the-art MCU control unit.
  • Precise, reliable, board mounted vacuum transducer.
  • Large LCD screen with large digits for highly visible, easy to read output.
  • Bright flashing Red LED Warning Light and Audible Warning Horn.
  • Rechargeable, long life, On-Board Battery Bank, (OBB).
  • Easy access replaceable 9V Lithium Battery Back-Up, (BBU).
  • Color segmented battery condition indicators for both On-Board and Replaceable batteries.
  • Fast, 2 hour, recharge of OBB, with optional AC/DC Charger/Adapter, (Part No. WS12DC).
  • Power Management logic; Operates directly and independently from 3 power sources, WS12DC AC/DC Adapter/Charger, OBB Battery Bank, or BBU Back-up Battery. (The OBB will automatically provide power when the AC/DC Adapter power is disconnected, and the BBU Battery will continue to power the VLS if the OBB Battery power is depleted.
  • Low battery “chirp” signal, when the VLS is disconnected from an AC power source and battery power is low.
  • Easily change vacuum units of measure between inHg and kPa.
  • Easy Push-to-Connect, ¼” vacuum fitting.
  • Rugged polycarbonate enclosure.
  • Plug-in auxiliary jack for connecting to the Anver VLS-AUX auxiliary alarm, or other peripheral devices

Vacuum Leakage Sensor and Warning Device

  VLS-09-20 Vacuum Leakage Sensor and Warning Device, Special 20% Version

The VLS-AUX is a peripheral device designed to be connected to the VLS vacuum loss sensor. When the VLS warning is activated, the VLS-AUX sounds a loud 105dB(A) siren and the flashing strobe is initiated. This add-on device is ideal for noisy environments, where the lifter is at a distance from the operator, or where other personnel may be in the general area of use.

This device has a self contained, easily accessible 9V battery and plugs directly into the AUX output port on the side of the VLS Vacuum Loss Sensor unit with a signal cable 25” [63.5 cm] long (included).

  • Large 105 dBa Alarm Siren and Bright Red Strobe Light
  • Plug-in input jack to connect directly to the VLS and VLS-20 Leakage Sensors.
  • Includes 25 inch [63.5cm] long signal cable with connectors.
  • Rugged polycarbonate enclosure.
  • Easy access 9V Battery Compartment.
  • Includes (1) Standard 9V Lithium Battery.

Note: VLS-AUX Auxiliary Alarm includes cable VLS-CAB-RJRJ which connects to all VLS-09 and VLS-08 models.
(If used with VLS-07, a VLS-07/08CAB must be ordered separately)
