Edwards Model 1575 Pressure Display

The Model 1575 Pressure Display is a low cost microprocessor based, digital display and set-point controller for the Barocel 600, 622 and 655 capacitance manometer. The Model 1575 incorporates power supply, digital display, four user-selectable set-points, along with analogue and optional RS232 output in a compact 1/8 DIN package.

Features & benefits

Push button or remote zero adjustment
- To adjust the transducer zero, simply press the front panel membrane switch. Alternatively, earth (ground) a rear panel connection.
Push button full scale calibration
- Use the full scale calibration feature if you want to display engineering units which are different from the transducer calibration, or to incorporate arbitrary coefficients for the transducer.
User selectable set-points with open collector contacts
- There are four user programmable solid-state, open collector set- points; two high and two low. The hysteresis band associated with each set-point can also be adjusted to meet system requirements.
Easy to read LED display
- The 10 mm bright red, high efficiency LED display is easily visible from normal viewing angle; and in most lighting conditions.
Optional RS232 output
- An RS232 port is available at minimal costs for digital pressure output
