Intrinsic safety explosion-proof small pressure sensor covers 0 to 10 kPa to 0 to 100 MPa!
The intrinsically safe explosion-proof small pressure sensor 23SYEi/25YEi is designed to meet advanced and diverse requirements in industrial applications, including pressure range, pressure connection, output signal, and electrical connection (25Y features a flush diaphragm structure; see the second photo). With a modular concept, this series offers high flexibility in specifications and can respond quickly with short lead times. A temperature sensor is integrated into the circuit, correcting errors due to temperature changes and contributing to improved overall accuracy. Standard types (non-explosion-proof types) 23SY and 25Y are also available. 【Features】 - Wide temperature compensation: ± 0.7 %FS @ -10 ~ 80℃ - Minimum pressure range starting from 10 kPa - Excellent long-term stability - Robust SUS housing 【Technology】 - Piezo-resistive pressure sensor - Welded structure without internal seals - Analog output: 4 ~ 20 mA, 0 ~ 5 V, 0 ~ 10 V, etc.
