SENSORS/ELECTRONICS: Sherborne Sensors’ Series T435 is a single-axis, high-precision, closed-loop, gravity-referenced servo inclinometer family designed for down-hole logging applications or for use in areas where space is at a premium. With a form factor measuring only 1.6 inch (40.6 mm) high and less than 1.46 inch (37 mm) in diameter, sensors can be stacked for simultaneous X and Y measurement of tilt angles. Models are available in ranges from ±3 to ±90 degrees. Series T435 offer a high-level dc output signal, proportional to the sine of the available angle of tilt. Units are fully self-contained and able to connect to a dc power source, and readout or control device for a complete operating system. The T435 series are also extremely rugged and can withstand a 1,500g shock event. Solder pin terminations are standard.
