Sino-Inst products

Sino-Inst SI-303 series high-precision low-pressure pressure transmitters adopt internationally renowned brand sensors. The measured pressure is converted into accurate electrical signals through high-performance amplifying circuits. The unique design of this product makes it resistant to environmental influences Unique play. Little affected by temperature change. Vibration resistance and good long-term stability. It is extremely suitable for engineering equipment, factory automation control and other fields.

Gauge Pressure Transmitter / transducer (GP) is a pressure transmitter for Gauge pressure measurement. Gauge pressure transmitter can measure the pressure of liquid, gas or steam. And convert it into 4 ～ 20mA DC signal output. The GP pressure transmitter can communicate with the HART Communicator, through which it can be set and monitored. Gauge pressure refers to pipeline pressure. “Gauge pressure” starts from atmospheric. Gauge Pressure plus atmospheric is the absolute pressure.

Piezoresistive Differential Pressure Transmitter uses integrated all-welded differential pressure measuring elements. Silicone oil is filled between the chip and the two corrugated diaphragms. This product utilizes the piezoresistive effect of semiconductor silicon materials. To achieve the conversion of differential pressure and electrical signals. The signal output from the Wheatstone bridge on the sensitive chip has a good linear relationship with the differential pressure. Therefore, accurate measurement of the measured differential pressure can be achieved. It is suitable for differential pressure measurement of various gases and liquids in petroleum, chemical.

LD series rigid rod-type liquid level sensor is sturdy and reliable. It is easy to install and does not need daily maintenance and calibration. Stainless steel measuring rods and floats are not affected by the physical and chemical properties of the liquid medium.

SI-U01 float level meter is composed of three parts: magnetic float, sensor and transmitter. When the magnetic float changes with the liquid level, it floats up and down along the duct. The magnetic steel inside the float attracts the reed switch at the corresponding position in the sensor. So that the total resistance (or voltage) of the sensor changes. The changed resistance (or voltage) signal is converted into a current signal of 4-20mA and output. And the upper and lower limit alarms can be set on the display to achieve the position control of the liquid level.

Ultrasonic Level Transducer, also called Ultrasonic level sensor, or ultrasonic level transmitter. Ultrasonic level transmitter is water level transmitter, which can measure Fluid level depth, oil tank level, with 4-20mA.

Magnetic Water Flow Meter provide highly accurate flow measurement for a wide variety of conductive fluid applications. Magnetic Water Flow Meter is a volumetric flow meter that measures liquids or liquid slurries that have a minimum conductivity of 5 µS/cm. Based on Faraday’s law of electromagnetic induction. Magnetic Water Flow Meter is ideal for wastewater applications or any dirty liquid which is conductive or water based. It is widely used in water treatment, environmental protection sewage measurement and control, papermaking and other industrial and agricultural production processes for flow measurement and control.

Gas turbine flow meter is a velocity flow meter that measures gas flow. For natural gas, nitrogen, and gas trade measurement.
The gas turbine flowmeter integrates temperature, pressure, flow sensors and intelligent flow totalizers. The gas turbine flowmeter has high accuracy and good repeatability, so it is suitable for trade measurement and industrial process detection. It is widely used in many kinds of gas in petroleum, chemical, metallurgy, aviation, scientific research and other sectors and industrial fields. Such as natural gas, city gas, propane, butane, air, nitrogen and other gases measurement.

Sheathed thermal resistance uses the feature that when the temperature of the material changes, its resistance will change too. When the resistance changes, the instrument will display relevant temperature corresponding to the resistance. It is usually used along with display instruments, recording instruments, electronic computers and so on. It is able to directly measure the temperature of liquid, steam and gas and solid surface within the range of -200℃～500℃.
