Sherborne Sensors T435 'L' Series Gravity Referenced Servo Inclinometer with 4-20mA Output

Product catalog summary

Features

Self-contained system requiring only a DC power source and a readout/control device.
Outputs a 4-20mA signal proportional to the sine of the tilt angle.
Available in ranges from ±3° to ±90°.
Rugged design capable of withstanding 1500g shock.

Applications

Ideal for bore-hole mapping, dam and rock shifts, and other geophysical, seismic, and civil engineering studies.
Suitable for applications with limited space.

Product Description

The T435 Series is a high precision, closed-loop, gravity-referenced tilt sensor designed for down-hole logging or space-constrained environments. It measures 61mm in height and less than 37mm in diameter, with solder pin terminations as standard. The 4-20mA output is designed for electrically noisy environments or long-distance signal transmission. It operates on a single 24 VDC supply with a maximum output load resistance of 400Ω.

Measuring only 61mm high and less than 37mm in diameter, models are available in a variety of ranges. Solder pin terminations are standard. The 4-20 mA, output is specifically designed for electrically noisy environments or where the inclinometer output signal must travel a long distance. The inclinometer operates on a single 24 VDC supply and the output series load resistance can be as high as 400D. The output current is proportional to the sine of the tilt angle.
