Fischer Germany MS12 series Digital Pressure Switch / Transmitter Fischer presents MS12 series Compact parameter driven pressure switch / transmitter for positive and negative pressure control Construction and Operation
The MS12 processes the output signal of the integrated pressure sensor digitally. A versatile parameter driven micro controller actuates on the display and the switching outputs. Optionally it produces a new output signal. The signal can be slewrate limited, spreaded, inverted, and transformed nonlinearly by means of a table function.
The parameters may be entered directly using the membrane sealed keypad or using a PC connected with a serial interface adaptor. Main Features
• Large bright LED display
• Selectable pressure units
• 2 independent limits with a choice of logic modes
• optional analogue signal output, with user-
• programmable scaling, linearization, inversion, and offset adjustment
• User-defined look-up table for signal conversion, with up to 30 points
• Fully programmable from a PC, using the optional Model EU03 PC Adaptor Applications
• Pressure switch / pressure display for un-convenient accessible measuring places
• Level measurement
• Simplified pump control
• Monitoring of pumps and compressors Technical: Measuring range (bar) : 0 - 1.6 bar to 0 - 60 bar Linearity < 1 % FS Hysteresis < 0.5 % FS Perm. ambient temp. -10 - +70 deg cel Perm. media temperature – 25 to + 80 deg cel (depending on the used gasket) Perm. storage temperature . -20 - +70 deg cel Protection class IP65 acc. to DIN EN 60529 Output signal 0 ... 20 mA, 4 ... 20 mA, or 0 ... 10 V DC (3-wire) Display 3½ digit LED
