Digital Suspended Solid Sensor
NS-SS682 （With Wiper）
Digital Suspended Solid Sensor
Product introduction
The water contains mud, silt, fine organic matter and other microorganisms and colloids that can make the water appear turbid. This product is to detect the suspended solid value in the water body by using the degree of obstruction of the suspended matter in the water to the light passing through. The infrared light wave sent by the transmitter on the sensor is received by the detector at a certain angle after being absorbed, reflected and scattered by the measured object during transmission. The internal calculation unit of the sensor uses a specific algorithm to calculate the value of the measured solution through the light intensity received by the detector. It is widely used in the monitoring of TSS in solutions of chemical industry, electroplating, papermaking, environmental protection water treatment engineering, pharmacy, food, etc. Especially suitable for use in the field and on-site.
Main features
- This digital submerged TSS sensor support RS485 signal and 4~20mA signal;
- The shell is made of 304 stainless steel + ABS material with certain corrosion resistance.
- The stable invisible near-monochromatic infrared light source is used to avoid the interference of the chromaticity in the liquidand the external visible light on the sensor measurement; and the built-in luminosity compensation improves the measurement accuracy.
- With automatic wiper cleaning function to reduce maintenance costs, the cleaning interval can be set for 1-30000 minutes.
- Using the latest detection technology to avoid the interference of external light, with strong anti-interference ability.
- Using quartz glass lens with extremely high light transmittance on the optical path, the transmission and reception of infrared light waves are more stable.
- Wide range, stable measurement, high precision, good reproducibility, not affected by sample flow rate and pressure.
- Communication function: Two-channel photoelectric isolation signal output, namely RS-485 communication interface (MODBUS-RTU protocol part compatible), the fastest communication interval time is 200ms; and 4-20 mA current output, 4-20 mA can be output in reverse; No meter is required, and it can be directly connected to computers, PLCs and other equipment with RS485/4-20mA signal interface for data collection. It is convenient for users to integrate sensors into industrial control environments such as host computer systems and IoT systems.
- Relevant settings for the sensor can be made through RS485 communication, slave address and baud rate, online calibration, factory restoration, 4-20mA output corresponding range, range modification, scale factor and incremental compensation settings.
- Using five-point correction method.
- Watchdog function: to ensure that the meter will not crash.
- Power-off protection>10 years.
