Product Introduction

Model 333C is a tri-axial piezo-electrical accelerometer permitting vibration measurements. 333C features an annular shear ceramic crystal which exhibits excellent output stability over time. Each axial of the accelerometer incorporates an internal circuit with in a two-wire system which transmits the 4~20mA current output through the same cable that supplies the voltage excitation. Signal ground is internal shielded and isolated from the outer case of the unit. Polarity inversion protection for the amplify circuit is inherent in the circuit design. The welded stainlesssteel construction provides a hermetic housing. The standard M12 5-pins connector provides long-term stability over the operating temperature range. In addition to adhesive mounting, 333C offer two through holes for screw mounting on the test object. The 333C provides wide frequency response and shock resistance, which is ideal for industrial vibration monitoring under incidental shock environment. Senther’s model 18T-L is a M12 5-pins connector mating cable for the sensor.
