▼Product Introduction
ZNNX-2100 is an intelligent rotary concentration sensor with an embedded system, industrial standard 4~20mA and RS-422 output, and can be calibrated on a control box or computer.
▼Measurement principle
The measurement is performed using pulp shear force.
▼Application areas
The rotary pulp concentration sensor has an advanced structure and is suitable for applications requiring high reliability and high precision.
▼Main features
ZNNX-2100 rotary concentration sensor has incomparable advantages over other forms of concentration sensors:
◆ Insensitive to pulp flow rate, air, pressure and vibration.
◆ Insensitive to changes in pulp composition, freeness, filler, black liquor content, etc.
◆ The installation location is not restricted. It can be installed almost anywhere in the process pipeline to obtain high-precision measurements, simplify the pipeline system and reduce installation costs.
◆ There is no slurry hanging phenomenon like ordinary thick adjustment, so frequent calibration is not required.
◆ Since it can be installed at the outlet of the pump, the closed-loop time from measurement to control is shortened and the real-time performance of control is improved.
▼Performance indicators
◆ Measurement principle: Measurement is made using the shear force of pulp.
◆ Working range: 1～10% concentration
◆ Sensitivity: better than ±0.005%
◆ Measurement accuracy: close to sensitivity under stable conditions.
◆ Pipe diameter: When the pipe diameter is less than 250mm, use a measuring chamber. When the pipe diameter is greater than 300mm, use a short joint.
◆ Installation method: It can be installed horizontally, vertically or on an inclined pipe. The sensor axis should be kept horizontal and the motor should be below the sensor.
◆ Flow rate: 0.5～5m/s
◆ Damping time: 1～100s
◆ Maximum working pressure: 1MPa at 80℃
◆ Ambient temperature: sensor maximum 60℃
◆ Shell: cast aluminum
◆ Parts in contact with the medium: The sensor, measuring chamber and short section are made of stainless steel.
◆ Motor: 3-phase 380VAC, 370W IP54
◆ Circuit working power supply: 20VAC
◆ Analog signal output: 4～20mA
◆ Load: 250～750Ω
◆ Digital signal output: RS-422
