CS-3 Two-wire Magnetic Resistance Speed Sensor Manufacturer

CS-3 Two-Wire Magnetic Resistive Speed Sensor

              Integrated with the functions of a transducer and a preamplifier, the ZA401 requires only a probe and an extension cable. By eliminating the need for a preamplifier, the number of components in the monitoring system is further reduced, significantly enhancing reliability. The ZA401 is a two-wire transmitter, meaning it must be connected to a PLC or DCS, with the host interface being an active one. Field connections are extremely convenient. The entire system operates with just double-line power from a PLC or DCS, greatly reducing costs for on-site installation, commissioning, and design. Installation is simple and straightforward; no adjustments are required.

Technical Specifications

Output Voltage Waveform: Cam gear – approximately sinusoidal wave; if the gear is slightly eccentric, it becomes amplitude-modulated sinusoidal wave; orifice plate – approximately square wave.

Temperature Range: -20℃ to 80℃ or (-30℃ to 130℃)

Thread Size: M16×1.0 or M16×1.5

Cable or Connector: Entire cable or with connectors

Measuring Range: 10 to 10,000 r/min (60 teeth)

Output Signal Amplitude: 30 RPM > 500 mV (Test Conditions: Transmission gear, 60 teeth, material: electrical steel)

Module 2, sensor face to tooth tip 1mm. Signal amplitude is directly proportional to the speed and inversely proportional to the gap size between the face and tooth tip.

Gear Material: High permeability material should be used.

Toothing: The involute toothing is the most suitable. Using large module gears or other toothing will result in significant wave distortion. This will hinder detection. If there is movement of the spindle in the axial direction, attention must be paid to ensure that the center of the magnetic pole is positioned over the gear.
 

GJ70 Magnetic Speed Sensor, Magnetic Resistance Speed ProbeInternally fitted with a magnet steel, the sensor generates an alternating voltage signal, approximately sine wave shaped, as it detects changes in magnetic resistance when there is a rotating magnetic gear or a disk (or shaft) with holes (or slots) near the core end face. The GJ70 magnetic-electric speed sensor features no power requirement, high output signal, good anti-interference performance, compact size, durability, reliability, and long service life, making it suitable for use in harsh environments such as smoke, moisture, oil, and gas.
