The pressure value is
always very small or
zero.
1.1 The tubes are bending or breaking Check the tubes and connection
1.2
The connection between the sensor
and transmitter is not firm
Check the electrical connection of
the sensor module
1.3
The pressure sensor got a problem
or the transmitter got a problem.
Please consult the manufacturer for
a warranty or replacement.

2.1
The lost connection between the
sensor and the transmitter
Check the electrical connection of
the sensor module
2.2 The sensor module got a problem.
Please consult the manufacturer for
a warranty or replacement.
There are no moving parts or consumed parts in the ULP Sensor. Therefore there is no need to do maintenance.
However, the pressure sensor will drift over time. We do recommend customer to re-calibrate it every 12 months.
This ULP Sensor has the default configuration. The user can change the configuration on the transmitter so that the
complete device ( transmitter) delivers the proper output values. Below are some configuration parameters
stored in the transmitter's flash memory.
Description Unit

CONSTANT_A 1 Float R/W
Constant a for scaling pressure value (in Pa)
CONSTANT_B 0 Float R/W
Constant b for scaling pressure value (in Pa)
HIGH_CUT 1E+09 Float R/W
High cut value for scaled value
LOW_CUT 0 Float R/W
Low cut value for scaled value
SENSOR_BOOT_TIME mS 200 Uint32 R/W
Boot time of sensor/input, in ms
TEMPERATURE_OFFSET_X10
