The sensor series "Modular Economic Sensors" is characterized by a very high flexibility concerning sensor equipment and the range of application due to its modular diversity. The ME series covers nearly all physical measuring categories like temperature, pressure, differential pressure, filling level, humidity and flow. In addition ultrasonic and infrared measurement round the programme. The ME series is modular designed so adaptable that it can offer an optimum modular device solution for the respective measuring job in cost-optimised base equipment, with limit switch, transmitter variants as well as with display full equipment, switch-points, radio controlled or with IO-Link for all industrial uses.
