1. Classification according to the way of engraving the disc is different
(1) Incremental type: that is, every time the angle of the unit is sent out a pulse signal (there is also a sine and cosine signal, and then it is subdivided, and the pulse with a higher frequency is chopped), usually the output of phase A, phase B, and phase Z, phase A and phase B are pulse output that are delayed by 1/4 period of each other, and the forward and reverse rotation can be distinguished according to the delay relationship, and the rising and falling edges of phase A and phase B can be multiplied by 2 or 4 times; The Z-phase is a single-turn pulse, i.e. one pulse is emitted per turn.
(2) ** value type: that is, corresponding to a circle, the angle of each reference sends out a ** and the angle corresponding to the binary value, through the external ring device can be recorded and measured in multiple positions.
2. According to the output type of the signal, it is divided into: voltage output, open collector output, push-pull complementary output and long-line drive output.
3. Classified in the form of encoder mechanical installation
(1) Shafted type: Shafted type can be divided into clamping flange type, synchronous flange type and servo mounting type.
(2) Bushing type: Bushing type can be divided into semi-empty type, full empty type and large-diameter type.
4. According to the working principle of the encoder, it can be divided into: photoelectric type, magnetoelectric type and contact brush type.

Zero drift of high-frequency pressure sensors – we are blessed
There are several reasons for the formation of zero drift of high-frequency pressure sensors:
1. There are bubbles or impurities in the adhesive layer of the strain gauge
2. The function of the strain gauge itself is unstable
3. There are virtual solder joints in the circuit
4. The stress release of elastomers is incomplete; In addition to the magnetic field, ...

How to choose a pressure sensor – we are blessed
1. Recognize the type of pressure measurement, that is, to measure the gauge pressure, absolute pressure or differential pressure. Gauge pressure refers to the pressure value with atmospheric pressure as the zero point, which can have positive and negative values, positive above atmospheric pressure, and negative below atmospheric pressure. The absolute difference refers to the pressure value with the vacuum as the zero point, and the absolute pressure is as long as the value is positive ...
