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 stability piezoresistive sensor die
Isolated construction, applicable to measuring various fluid

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.

The paper machine's drying section employs steam-heated cylinders, with steam generated by a separate boiler and transported by pipelines. To ensure optimal steam supply, a differential pressure transmitter with an orifice plate is used to measure flow, allowing for accurate planning.

The pulp undergoes high-temperature bleaching in a tower using peroxides, ozone, or oxygen to get the right white color. The tower usually stays empty while the large amount of bleached pulp is dumped via a screw conveyor.
