Fieldbus pH/ORP transmitter APM-1

serialdigital outputanalog output

The compact transmitter /controller APM-1.. measures and controls the pH value or redox potential in aqueous solutions. It is available as panel-mounted device according to DIN/EN 61554 or as field housing. Measured values and parameters are displayed on a highcontrast graphic display in plain text. Easy configuration via buttons or PC with optional software provide a simple and user friendly operation. An integrated math and logic module enables the integration of the measured values in mathematical formulas so that the measured variables can be displayed. Measuring range: pH: -2 ... 16 Redox: -1500 ... +1500 mV Pt100 / Pt1000: -50 ... +250°C Standard signal: 0(4) - 20 mA / 0 - 10 V Resistance: 100 Ω - 3 kΩ Input: 1x pH/Redox 2x binary inputs 1x temperature / resistance / standard signal Output: 2 relays (SPDT) 1 x power supply for 2-wire sensor 17 VDC Optionanl plug-in boards: analogue output, power supply, RS485, data logger, Profibus® PA, relays Graphic display with backlight (max. 3 values, trend, bargraph), supply voltage for 2-wire sensors, freely programmable, math and logic module, with panel mounted housing or field mounted housing
