The output of BSIL-W10-DM Liquid Level Sensor is RS485 (MODBUS) digital signal, so each sensor is connected to each other by means of a four-wire bus cable.. The same cable(customer specified length) connects the uppermost sensor to the chosen readout (PC or datalogger, system, etc.)

The Vibrating Wire Load Cell is designed to directly measure load in piles, rock bolts and between tunnel supports, as well as tension in cable anchors.

The main component is a cylindrical weight suspended from the force transducer. The cylinder hangs partially submerged in the water whose level is to be monitored. As the water level changes the changing buoyancy force on the cylinder acts directly on the vibrating wire transducer and alters its tension and hence its resonant frequency.

The Vibrating Wire Embedment Jointmeter comprises two parts; a socket and a main body. The socket is a detachable end that is cast into the first concrete lift. The main body is a protective outer case which houses a Vibrating Wire displacement transducer and screws into the socket. Once screwed into the socket, it is cast into the second lift of concrete.

The Vibrating Wire Strain Gauge measures strain in steel members. The gauge consists of a coil assembly, Vibrating Wire element and two weldable anchors.The strain gauge incorporates O-ring seals to provide waterproofing, and allows the tube to remain unstressed. A factory fitted, four core screened cable connects the coil to the readout unit.
