Setup
General
To obtain maximum accuracy from your Type 631D transducer, be sure the interconnecting
piping and the transducer components themselves are properly installed. Some general guidelines
are:

Mount the transducer such that vibration, shock, and temperature fluctuations are
minimized, and that the product’s inlet always points downward or horizontally.

Minimize interconnecting piping

Ensure adequate room to maintain environmental requirements and safety considerations,
and to provide easy access for calibration
Environmental Considerations
The 631D high temperature transducer is designed to operate at its specified operating
temperature. To meet this high operating temperature, you must follow these guidelines:

DO NOT use a thermal blanket on the 631D transducer
The addition of a thermal blanket will cause the electronics to overheat.

Provide adequate air circulation
Sufficient air circulation is necessary to prevent heat buildup within the transducer.
