LEEG Flush diaphragm pressure sensor SP19FR

Product catalog summary
Overview: The SP19FR Flush Diaphragm Piezoresistive Single Crystal Silicon Pressure Sensor is designed for high overload protection and is suitable for industries requiring CIP/SIP cleaning, such as food and pharmaceuticals. It features an isolated air cavity to prevent condensation and contamination.
1. Parameters: The sensor has a measuring range of 0~100kPa to 35MPa, with a power supply requirement of ≤2.0mA DC. It features gold-plated kovar pins or silicone rubber soft wire for electrical connection, and has an input and output impedance of 3kΩ to 8kΩ. The response time is less than 10ms for certain conditions, and it can withstand an overload of 1.5 times its full span.
2. Structure: The diaphragm and housing are made of Stainless Steel 316L, with an FKM O-ring.
3. Environmental Conditions: The sensor is designed to handle deviations in position, vibration, and impact without significant changes in performance. It is compatible with fluids that do not react with its structural materials and FKM.
4. Basic Conditions: The sensor operates optimally at a medium and ambient temperature of 22±2°C, with a humidity of 50%±10% RH and atmospheric pressure of 86 to 106 kPa.
5. Basic Specifications: The sensor's accuracy is defined by nonlinearity, repeatability, and hysteresis, with a compensation temperature range of -10 to 80°C and an operational range of -20 to 125°C. Long-term stability is ±0.2% F.S./year.
6. Configuration: The sensor is available in different configurations for process and body connections, with specific order codes for customization.
7. Electrical Connection: Options include gold-plated kovar pins or silicone rubber soft wire for pressure resistance signal output.
8. Ordering Information: The document provides detailed codes for specifying model numbers, pressure ranges, connection types, and output signals. Selection hints emphasize the importance of avoiding damage to the diaphragm and compensation circuit board, and the need for consultation if operating outside standard temperature ranges.
