采购商询盘内容
We are looking for high-quality electrochemical sensors designed for gas detection. The sensors should cover detection ranges of either 0-100 ppm or 0-300 ppm, with an accuracy of ±5% FS at 25°C, and a typical accuracy of ±10% FS within the range of 5-50°C. Quick response time is essential, targeting T90 at 60 seconds. Output signals need to include 4-20mA (2 wires), 0-10VDC, and RS485/Modbus compatibility.
Power input should be versatile, supporting current inputs of 18.5VDC-35VDC and voltage inputs of 16-28VAC or 16-35VDC. The housing material should be fire-retardant PC or ABS+PC (UL94V-0) and provide at least an IP33 rating for protection. Operationally, the sensors should function effectively in temperatures of 5-50°C, with a relative humidity range of 15-90% (non-condensing). Additionally, ensure that the products are CE approved. We require a total of 150 units.
