Special Conditions for Safe Use
i.
Since models AST4300 and AST43LP Pressure Transducers are not earthed and a charge-generating mechanism may be
present when in contact with non-metallic charge generating materials, the device shall be grounded before use.
ii.
This product is manufactured from light metal and in rare cases, potential ignition sources or sparks may result due to
impact or friction. User is recommended to use caution during installation, particularly if the equipment is utilized in Zone 2
locations.
iii.
The product label indicates that the process temperature range is -40°C to +125°C. Taking this into account, the
user/installer shall take the precautions to ensure the operating service temperature of the overall pressure transducer
assembly is between -40°C to +92°C.
Process Connection Installation
For threaded installations, use the 7/8” hex above the thread of the process
connection to install the process. Do not use the body / housing for installation.
Maximum working pressure for the lowest pressure sensors 0.34MPa (50 psi)
and maximum working pressure for the highest pressure sensors 137.9MPa
(20,000 PSI) -- SINGLE SEAL.
