QE-9 pressure switch intelligent pressure switch application areas such as water, electricity, running water, petroleum, chemical, mechanical, hydraulic characteristics of the industry switch can be set anywhere between zero to full scale shell has to behave like light-emitting diode, more easy to observe way switch, portfolio of analog signal output, Profile QE-9 Series pressure switch, stainless steel nozzles, has a strong anti-corrosive. The shell is made of stainless steel or hard aluminum (black anodized). The sensor in a wide temperature range, the temperature compensation to ensure that the sensor specifications. Voltage output 0/0.5/1 ~ 4/4.5/5/10VDC, and switch control output for the relay output (QE-9: 120VAC × 1A or 24VDC × 1A, QE-10: 230VAC 5A or 24VDC × 5A) level output or transistor output. Pressure port thread form and wiring, the maximum to meet customer needs. Widely used in gas / liquid pressure measurement and control systems, industrial equipment, medical equipment, refrigeration equipment, constant pressure water supply, and process control fields. The QE family includes the QE-9, the QE-10 two sub-series, see selection table. Matching our R & D and production of a variety of measurement and control instruments or circuit module.
