During work on and with the device, the required personal protective equipment must always be worn. Appropriate use The VF-95 is a sensor for point level detection. You can find detailed information about the area of application in chapter "Product description". Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions.
That is why we have introduced an environment management system with the goal of continuously improving company environmental pro- tection. The environment management system is certified according to DIN EN ISO 14001. Please help us fulfil this obligation by observing the environmental instructions in this manual: • Chapter "Packaging, transport and storage" • Chapter "Disposal" 925-0376 VF-95 • Vibrating Fork...

Solid detection in water If VF-95 was ordered for solids detection in water, the tuning fork is set to the density of water. In air or when immersed in water (density: 1 g/cm³/0.036 lbs/in), If VF-95 signals "uncovered". Only when the vibrating element is also covered with solids (e.g.

DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. Switching point In general, If VF-95 can be installed in any position. The instrument only has to be mounted in such a way that the vibrating element is at the height of the desired switching point.
Mounting instructions Mounting socket The vibrating element should protrude into the vessel to avoid buildup. For that reason, avoid using mounting bosses for flanges and screwed fittings. This applies particularly to use with adhesive products. Filling opening Mount the instrument in such a way that the tuning fork does not protrude directly into the filling stream. 925-0376 VF-95 • Vibrating Fork...

A spout forms in the concave protective sheet preventing wear of the protective sheet. Horizontal mounting To achieve a very precise switching point, you can install VF-95 horizontally. However, if the switching point can have a tolerance of a few centimeters, we recommend mounting VF-95 approx. 20° inclined to the vessel bottom to avoid buildup.

4 Mounting VF-95 at a position in the vessel where no disturbances, e.g. from filling openings, agitators, etc., can occur. Product flow To make sure the tuning fork of VF-95 generates as little resistance as possible to product flow, mount the sensor so that the surfaces are parallel to the product movement.

(1) It is already preset and must only be modified in special cases. By default, the potentiometer of VF-95 is set to the right stop (> 0.02 g/cm³ or 0.0008 lbs/in³). In case of very light-weight solids, turn the potentiometer to the left stop (> 0.008 g/cm³ or 0.0003 lbs/ 925-0376 VF-95 •...
