WARNING - READ BEFORE INSTALLATION
Vaisala Differential Pressure Transmitter PDT101 is a high-performance
instrument designed primarily for use in life science and cleanroom
applications. PDT101 is not authorized for use as a critical component in life
support devices or systems. Consult Vaisala before installing if there are any
questions or concerns.
Overpressure: Pressure spikes in excess of the rated overpressure capability
of the transmitter may cause irreversible electrical and/or mechanical damage
to the transmitter.
Static electrical charges: To avoid damage to the transmitter the
operator/installer should follow proper ESD (electrostatic discharge)
protection procedures.
