Description
SEIKA SB1S Sensor box containing one sensor, one signal conditioner with 0…5V output and two open-collector output switches.
The SB1S Sensor box is a pressure die cast aluminium sensor housing (IP65) with an integrated sensor for measuring uniaxial acceleration or inclination.
As well as the sensor, the box contains a signal conditioner with a 0 … 5V output and a separate, highly stable supply voltage that can be used externally as a reference point. Furthermore, the signal conditioner includes an active low pass filter, whole upper cut-off frequency / settling time can be tailored to suit the measurement task, and a noise voltage filter to guarantee the EMC. Interference signals caused by unwanted ground currents are eliminated by electrically isolating sensor and signal conditioner from the housing.
In addition to the voltage output, the SB1S has two open-collector output switches. Two helical trim-potentiometers enable the adjusting of two trigger thresholds within the measuring range, the exceeding of which causes the corresponding output switch to trigger. Optionally, the state transition can be set to be either off to on or on to off. The switching hysteresis can be adapted to the measuring task.
Unlike the SB2.., the SB1S can accommodate larger inclinometers, such as the NG-series, that have a higher measuring accuracy. A special electronic temperature compensation system can significantly reduce the temperature sensitivity of the implemented sensor.
The compact PG 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.
