Frequently Asked Questions (FAQ)
Q1. What is the CAMLogic GVS25 Series used for?
The GVS25 Series is designed for level detection of powders and granular solids in silos, hoppers, and tanks. It provides reliable indication of maximum or minimum material levels and can detect materials with densities as low as 0.2 kg/dm³.
Q2. What are the main models in the GVS25 Series, and how do they differ?
- GVS25: Standard threaded version for general-purpose installations.
- GVS25F: Flanged version for secure mounting in heavy-duty or large vessels.
- GVS25AT: High-temperature version, capable of operating up to +200°C.
Each model shares the same sensing principle, electrical configuration, and performance quality, but differs in mounting type and temperature capability.
Q3. How does the vibrating fork detection principle work?
The instrument’s stainless-steel fork vibrates at a specific frequency. When material covers the fork, the vibration changes, triggering a signal that indicates a full (covered) or empty (uncovered) condition. This simple and robust technology ensures accurate and maintenance-free level measurement.
Q4. Is calibration or adjustment required during installation?
No calibration is required. The GVS25 Series comes factory-calibrated and ready for use. Installation involves mounting the device, connecting the power supply, and selecting the desired failsafe mode and sensitivity via the internal switches.
Q5. What materials are suitable for detection with the GVS25 Series?
The GVS25 Series works with powders and granular materials such as cement, flour, sugar, sand, plastic pellets, ceramics, and recycled materials. It is suitable for low-density materials starting from 0.2 kg/dm³ and particle sizes up to 10 mm.
Q6. Can the GVS25 Series operate in high-temperature environments?
Yes. The GVS25AT model is specifically designed for process temperatures up to +200°C, making it ideal for applications in hot material storage or heat-affected zones.
Q7. What is the difference between the failsafe high and failsafe low modes?
- Failsafe High (switch OFF): The relay remains energized during normal operation and de-energizes in case of alarm or power failure – used for maximum level control.
- Failsafe Low (switch ON): The relay is energized when the material is absent and de-energizes when material covers the fork – used for minimum level control.
Q8. What electrical configurations are available?
The GVS25 Series features a DPDT (Double Pole Double Throw) output and supports both AC (15–260V) and DC (15–80V) supplies. The contact rating is 5A at 220V AC or 24V DC, suitable for direct control of alarms or intermediate relays.
Q9. What maintenance does the GVS25 require?
The GVS25 Series is maintenance-free under normal conditions. A visual inspection of the lid gasket (O-ring) is recommended when the cover is opened. If damage or wear is found, replacement with original CAMLogic parts is required.
Q10. What protection ratings does the device have?
- Casing: IP65 – dust-tight, protected against water jets.
- Wetted Parts: IP68 – dust-tight, protected against continuous immersion.
These ratings make it suitable for both indoor and outdoor industrial applications.
Q11. Can the GVS25 Series be installed in any orientation?
Yes. The indicator can be mounted vertically, horizontally, or at an angle. When installed on the side of a vessel, the fork tines must be oriented vertically to ensure correct operation.
Q12. What is the warranty period for the GVS25 Series?
All CAMLogic GVS25 level indicators are covered by a 24-month warranty from the date of shipment. The warranty applies to material or manufacturing defects only and is void if the product is tampered with, misused, or repaired by unauthorized personnel.
Q13. Who supplies CAMLogic products in the UAE and MENA region?
The official distributor for CAMLogic products, including the GVS25 Series, in the UAE and MENA region is Dubai Sensor, providing local availability, product guidance, and after-sales support.
