Sensor Technology
MPS1 Multiparameter Sensor
DPT145 combines Vaisala’s proven DRYCAP® sensor technology
for industrial dewpoint measurement with BAROCAP® pressure
sensor technology. Both technologies are integrated on the same
MPS1 multiparameter sensor element, allowing for a highly compact
and versatile transmitter.

MPS1 Sensor
There are several important advantages in using a transmitter with an
integrated sensor:
- Reduces installation work and cost.
- Improves the leak tightness of the system as connection points are
minimized.
- Enables online monitoring of all supported parameters.
DRYCAP® Technology
Vaisala DRYCAP® dewpoint measurement technology ensures
accurate measurement with excellent long term stability. This results
in very low maintenance requirements for the transmitter. The lasting
performance is achieved with microprocessor technology and
software that automatically performs self-diagnostic functions in
addition to the normal dewpoint measurement. The self-diagnostic
procedures that are conducted are called auto-calibration and sensor
purge.
