Sensor selection:
First, according to the structure:
1. Single-point sensor (single point load cell): platform scales
2. Single shear beam sensor (single shear beam load cell):floor scales, weighing module, hopper scales, belt scales, axle scales, etc.
3. Pull the sensor (Tension load cell): crane scale, test equipment, overload protection
4. Double ended load cell: truck scale, railroad scale, crane scale, hopper scale, overload protection, etc.
5. Pressure sensor (Compression load cell): truck scale, track scale, axle weighing, test machine, hopper scale, pile driver, overload protection
Second, according to the elastomer material:
1. Stainless steel: mainly used in food, chemical, pharmaceutical and other corrosive environment of the place;
2. Alloy steel: suitable for non-corrosive environment;
3. Aluminum alloy: generally for small weighing need and normal weighing application.
Third, according to the output data
1.Analog sensor: the output is analog signals, such as voltage, current, etc;
2.Digital sensors: direct output of the digital signal , such as kilograms, tons and so on.
Fourth, according to the applicable temperature.
1.Usual temperature: used in conventional places, no special requirements for temperature;
2.High temperature: used in metallurgy, nuclear power and other high temperature (generally above 100 ℃) environment;
3.Low temperature: use at temperatures below -30 ℃ place, such as freezing test.
Fifth, according to the accuracy level: With reference to OIML R60 recommendations, the products of our company is mainly C class, n = 3000
Six, according to the output resistance.
1. High impedance: ≥ 1000Ω
2. The standard impedance: less than 1000 ohms, commonly 350Ω, 700Ω
