Description
The SBS1U is a pressure die cast aluminium sensor housing (IP67) with an integrated sensor for highly sensitive, uniaxial acceleration or inclination measurements.
As well as the sensor, the housing contains a signal conditioner with ±4 Volt output and a separate, highly stable voltage supply. Furthermore, the signal conditioner includes active low pass filters for suppression of interference signals and transient suppression for EMC guarantee. Interference signals caused by unwanted ground currents are eliminated by electrically isolating sensor and signal conditioner from the housing. The terminals provide either two mutually inverse asymmetric 0.5 ... 4.5 Volt or one symmetrical ±4 Volt output voltages.
The compact metal cable gland and small housing size in combination with the max. 6-wire connection enable the use of this high quality measuring system in harsh operating conditions.
Application
The SBS1U is suitable for applications requiring extremely precise inclination measurements under harsh operating conditions and an analog signal output. Typical areas of successful application include stability monitoring of buildings and machinery and inclination monitoring on bridges, dams, towers, tunnels, slopes and structures in danger of collapse or earthquakes.
