Product Description
The capacitance level sensor measuring principle is base on the " capacitance effects " , when this level sensor is set on a silo, it will be formed a condenser between the detector electrode and the silo wall. The capacitance of this condenser varies proportional to the change of material specific inductivity ( DK value) of the material stored in the silo , when the more material substances increased in the silo, the more capacitance value added simultaneously, then it will let his interior circuit "s resonant signal to create a bigger amplitude ,and such a signal amplitude become more or less than factory default threshold value, the relay device will be energized.
- No moving parts inside the device, it will be not affected by friction, which are suitable for powder or liquid application.
- Various models are suitable for different application.
- Operating temperature -20 ~ 200°C, Max. 800°C.
- The sensitivity, which includes 10pf, 20pf and 40pf, is adjustable.
- With timing delay design, timing adjustable range 0 ~ 6 seconds.
- Voltage: 110V/220VacC or 24Vdc
- Output: NPN transistor, 5A/250Vac and 5A/240Vac SPDT contact.
- Standard connecting screw 1" NPT, special specification are acceptable.
- Enclosure protection IP65 or explosion-proof.
- SA-75U Zener barriers inside provide intrinsic safety (Ex ia IIC) to SA17( )D type level switch.
As Capacitance Level Switch has no moving parts inside the device, it will not be affected by friction. It is suitable for powder or liquid application easy to install. The customer can choose the types for his requirements.
- Standard Type:Suitable for general use.
- Hi-Temp Type:Suitable for high temperature environment.
- Anti-Corrosion Type:Suitable for corrosive environment.
- Remote Probe Type:For use with vibrator equipped with tank.
- Wire-Probe Type:Suitable for silo or large-size tank.
- Plate-Probe Type:Suitable for granules and at lower position of tank side.
- Explosion-Proof Type:Ex dia II C T4~T6, DIP A21 TA,T3~T6
- Explosion-Proof Type:Ex ia IIC T3~T6. ( Equipped with SA-75U signal conditioner can be used in hazardous areas.)
- Anti-Static Type:Suitable for electrostatic environment. ( It won't be damaged by the electrostatic discharge.)
