Inclination Measurement Tools  Manufacturers, Traders, Suppliers

Since its foundation, EFCO has developed into a leading developer and manufacturer of repair and testing technology - both in terms of market share and technological progress. The products are sold in over 80 countries by the company`s own sales organisation and competent partners.
All products are developed in-house and tested in practice. Experience gained from the use of many clients flows directly into product development. Maintaining the production and development site in Germany is one of the top priorities. EFCO rightly stands for the quality label ‘Made in Germany’ and has been TÜV CERT ISO 9001 certified since 1996.
The family-run company is managed by the second generation of an experienced management team. EFCO specialises in precision machines and equipment for the repair and processing of sealing surfaces on valves, flanges and pipelines. Through innovative developments and the exchange of know-how with clients, EFCO has established a precautionary repair culture that enables significant economic savings.
The product portfolio includes
- Transportable grinding and lapping machines for sealing surfaces on valves and gate valves
- Transportable turning technology
- Stationary grinding and turning technology
- Flat lapping machines
- Transportable testing devices for safety valves
- Mobile and stationary valve test benches
- Spare parts and consumables for repair, maintenance and testing of valves

Capacitive inclination sensors consist of 2 chambers designed as capacitors which are filled with an oil as dielectric. As a result of the change in inclination, the viscous oil runs from one chamber of the inclination sensor to the other chamber, thereby creating a change in capacity. Both capacitors are differentially connected. The integrated electronics converts the change in capacitance of the inclination sensor into a voltage signal proportional to the inclination.
In this design, the inclination sensors provide the measuring signal for 1 measuring axis, the measuring range is +/-45 degrees. In a dome-shaped version with 4 capacitors, the inclination sensor can directly provide measured values for 2 measuring axes, but the measuring range of the inclination sensor is reduced to 20 degrees.
ALTHEN uses these inclination sensors and installs the inclination sensors together with amplifier electronics in an aluminium die-cast housing. This results in a flexible inclination measuring system that can be used very well for industrial applications in harsh environments. The amplifier electronics are available as voltage (5 V or 10 V) and current amplifier (0 or 4...20 mA). The scaling can be selected between +/-3 and +/-45 according to customer specifications. By grouping 2 individual inclination sensors over a rigid 90 degree angle, the 1-axis inclination sensor can also be turned into a 2-axis measuring system.
In a special ATEX-approved version, the 1-axis measuring system can also be used as an intrinsically safe version in hazardous areas. Due to the modular design, consisting of inclination sensor and additional electronics, the measuring system is also very well suited to the requirements for use in customer-specific applications.
