Keller Company Essential Safety Explosion-Proof Low Pressure Sensor Series 41X-Ei
Low pressure intrinsic safety explosion-proof pressure sensor achieves high precision!
The capacitive pressure sensor series 41X-Ei is designed to measure gauge pressure in low-pressure ranges. Through a mathematical correction method, it achieves high accuracy of ±0.2 to 0.3% FS in low-pressure measurements within a temperature range of 10 to 50°C. In addition to a digital RS485 interface, analog current or voltage outputs are also available. 【Features】 - Although calibrated in the standard range, programming of the analog output signal within the standard pressure range is possible using the license-free software CCS30 (e.g., standard pressure range 0 to 10 kPa/output 4 to 20 mA → pressure range 2 to 6 kPa/output 4 to 20 mA). - Using software CCS30 and converter K-114, pressure values can be displayed on a PC, allowing for recording of pressure signals, graphical display, and zero adjustment. - Up to 128 transmitters can be connected to the bus system. - Intrinsically safe explosion-proof type.
