SY-2088W Input-type Liquid Level Transmitter

 

Specification:

 

Overview:

SY-2088W Input-type liquid level transmitter can be used for the petrochemical industry, metallurgy, electric power, pharmaceuticals, water supply and drainage, and environmental protection system and the industry level measurement of a variety of media.

Compact structure, simple installation and flexible adjustment for users to easily use.

4 ~ 20mA, 0 ~ 5v, 0 ~ 10mA standard signal output as required by the user choose.

 

Working Principle: With hydrostatic measuring principle: When the liquid level transmitter into a  measured depth of the liquid, the sensor surface pressure Ying formula: = ρ. GH + Po Where: P: Ying-level pressure transmitter ρ: liquid density measured g: the local acceleration due to gravity Po: the atmospheric pressure liquid H: the depth of the liquid transmitter input At the same time, through the introduction gas make stainless steel liquid pressure into the sensor cavity, and then the atmospheric pressure Po on the surface and cavity pressure sensors connected to the back of the sensor offset Po, so that pressure sensor measured: ρ. gH, obviously, through the measured pressure P, can bedeep level.

 

Features: 1. Good stability, and full-scale, long-term stability of zero up to 0.2% FS / year. Compensation temperature range of 0 ~ 70 , the temperature drift less than 0.2% FS, in the entire allowed operating temperature range of less than 0.5% FS. 2. With reverse protection, current limiting protection circuit, are negative in the installation will not damage the anti-access transmitter, abnormal sent automatically when the current limiting in less than 35mA. 3. Solid-state structure, no moving parts, high reliability, long service life. 4. Convenient to install, simple structure, economic and durable.

Debugging methods: Screw under the protective cover, you can see the zero and full-range resistor, power supply and ammeter external standards (0.2 extremely above) can be adjusted, follow these steps: 1. There is no liquid in the transmitter, the zero adjustment resistors, so that output current of 4 m A, 2. Transmitter plus full-scale solution to regulate the full range resistor so that the output current 20 m A, 3. Repeated two or three times the above steps until the signal to normal. 4. Adjustment completed, tighten the protection cap.

Note: 1. Where products are available with the use of manual and certification, including product code, technical parameters, such as ex-factory date, please check carefully to avoid the wrong. 2. Access should be strictly in accordance with the power supply cable instruction provide by our company. 3. Abnormal use, should switch off the power, to stop using, check, or directly to contact with the company's technology department. 4. Transport, storage should be the restoration of the original packaging, stored in a cool, dry, ventilated coffers. 5. 18-month warranty.
