SYSTEM DESCRIPTION OF THE F053-A
Functions and features
The pressure monitor model F053-A is a microprocessor driven instrument designed to display the
actual pressure as well as the monitoring of the pressure for high / low values.
This product has been designed with a focus on:
▪
ultra-low power consumption to allow long-life battery powered applications (type PB / PC),
▪
intrinsic safety for use in hazardous applications (type XI),
▪
several mounting possibilities with GRP, aluminum or stainless steel 316L enclosures for
industrial surroundings,
▪
ability to process all types of sensor signals
▪
transmitting possibilities with one configurable alarm output.
Sensor input
This manual describes the unit with an analog (0)4-20mA input type from the sensor "-A version".
Other versions are available to process 0-10V sensor signals.
One sensor with a passive or active (0)4-20mA signal output can be connected to the F053-A. To
power the sensor, several options are available.

Configuration of the F053-A
The F053-A has been designed to be implemented in many types of applications. For that reason, a
SETUP-level is available to configure your F053-A according to your specific requirements.
It includes several important features, such as span, measurement units, display options etc. All
setting are stored in EEPROM memory and will not be lost in the event of power failure. To extend
the battery-life time, please use of the power-management functions as described in chapter 3.3.5.
Display information
The F053-A has a large transflective LCD with all kinds of symbols and digits to display measuring
units, status information, trend-indication and key-word messages.
Pressure and alarm values are displayed with the large 17mm digits while the smaller 8mm digits
can be set to display the measuring unit.
Options
The following options are available: intrinsic safety, mechanical relay, passive or active outputs,
power- and sensor-supply options, panel-mount, wall-mount and weather-proof enclosures, flame
proof enclosure and LED backlight.
