INCLINOMETER

 

SB1U

Sensor-box with one Sensor and one amplifier for:

2.5Volt +/- 2Volt 
signal output with working ranges:
+/-10 - +/-30 - +/-80

Special features


Description

The SB1U sensor box is a pressure-cast aluminum box ( IP65) with integrated sensor for single axis Inclination or for Acceleration measurement.

The SB1U contains an amplifier part with 0…5VDC output signal possibility, also as a separate part on the board there is a high-stable power supply for supplying the actual sensor ( this can also be taken out as an ref. Voltage ! ). The amplifier for the Signal output, contains also a low-pass filter for upper frequencies limitation. Rise-time constant as a specific value, + an max. current output limitation, can also be a part of the custom built unit. Supply noise suppression filter and diode bridge for guarantee of the Electromagnetic Compatibility are also a standard part in this unit. Sensor and amplifier are galvanic isolated from the housing.

In the SB1U box can the NG or NB3 type sensor also be implemented, which means a very high degree of a accuracy on the measuring of inclination and an considerably reduced temperature drift over the whole temperature range, this as the highest degree of accuracy of all SEIKA products.

A strong metal PG cable gland and the solid and compact housing for the whole Sensor box in connection with the high voltage signal output gives al together a high-quality system for use under many types of difficult working conditions.

Applications

The SB1U is used everywhere, where inclination or acceleration measurements are wanted together with a high level DC voltage output. In particular in buildings, mining industry, radar systems, bridges, ships, in agricultural machinery and in all types of process machinery, just name IT ! and SB1U can be for very good use everywhere.
