SP38H
Used For
Process Control, Environmental control, Flow control
Leave a MessageLEEG, a subsidiary of MICROSENSOR, is a leading manufacturer of hygienic transmitters in China's food and pharmaceutical industries. The SP38H Sensor adopts high-reliability monosilicon technology, with a built-in temperature sensor, which greatly improves the temperature performance. It is a comprehensive digital and smart sensor. It is resistant to high pressure and high static pressure, the static pressure can reach 40MPa. It can be used in various harsh environments, and the working temperature range is as high as -40-85°C. The pressure sensor also has the features of high measurement accuracy, high stability, strong output signal, and good long-term stability.
Features
• Three-diaphragm overload structure
• High long term stability <±0.05% F.S./year
• Extremely low pressure and temperature hysteresis
• Built-in temperature sensor
• Various of isolated diaphragms to meet a wide range of anti-corrosion requirements
• Rugged construction with little effect of repackaging stress
Electrical Performance
• Power supply: 2.5-12VDC
• Electrical connection: 110mm silicone rubber soft wire/Kovar Pins
• Common mode voltage output: 50% of input (typical)
• Bridge resistance: 6kΩ±0.5kΩ
• Response time (10%-90% ): <2ms
• Insulation resistance: >100MΩ@500VDC
• Insulation strength: <5mA/500V AC

High-speed paper mills use a vacuum system with turbine blowers to facilitate dewatering. The vacuum level, which is controlled by motor speed, must be continuously monitored. In addition, to ensure safe vacuum pump/blower operation, the lubrication status of bearings is maintained by measuring lubricant pressure and reservoir level.

Sump wells are important facilities for convenient daily inspection, prevention, and dredging of drainage pipe blockages. By deploying monitoring instruments at the bottom of the well, a comparison of drainage volume and rainfall is made, allowing for the prediction of flooding points and drainage times under real-time changing drainage conditions. When the water level data exceeds the preset warning value, a timely alarm is given, effectively preventing urban flooding.
