When Hengstler set about developing a new counter for commercial gas and water metering applications, the company had two main objectives: to make it self-powered to overcome the limitations of both power supply availability and battery-operated devices; and to make it resistant to tampering using magnets that interfere with the mechanical meter register found in conventional counters. The fruit of Hengstler’s research has seen the company introduce its SPC (Self-Powered Counter) to the global market. Simple, innovative and cost effective, SPC comes with ATEX certification and offers class-leading shock and vibration resistance.

Offering dimensions of 70 mm depth and 59 mm diameter – typically half the size of conventional explosion-proof encoders – the new ACURO^® AX65 encoder from Hengstler will prove extremely valuable to system designers seeking space-saving solutions (image 1). Furthermore, the fact that the device can be replaced separately from the cable, the presence of fewer hood screws, and the potential for ring network configuration (less wiring), makes the AX65 an attractive proposition for customers looking to lower their total cost of ownership (TCO).
