Installation

1.Pre-installation inspection

( 1) The test pressure must not exceed the upper limit of the measurement range of
the transmitter.
( 2 ) with the measured medium is adapted to the structural material of the transmitter , does not corrode .
( 3 ) whether the measured medium temperature exceeds the operating temperature
range of the transmitter .
2. Installation
( 1 ) pressure transmitter is mounted vertically , can be installed directly on the pipeline pressure test port.
( 2 ) directly into liquid level transmitter can be used , attention fixed firmly to the wire ,moving water installation should take hydrostatic devices.
( 3 ) junction box or the wire connections to take anti-rain treatment .
( 4) The junction box should be grounded .
Note: The transmitter housing with junction box mounting hole size is M6 × 1, 32m
pitch
3. Pressure Transmitter Installation Precautions
(1 ) pressure transmitter pressure interface , the force must be exerted on the lower part of the six-party transmitter , can not be directly screwed the top of the electron shell , so broken inside the transmitter leads.
( 2 ) If there is no standard pressure source user , do not self-adjusting zero and span potentiometers.
( 3 ) If the transient overvoltage or frequent shocks ( such as water hammer , etc. ) in the presence of the pipe or vessel buffer device should be installed to prevent damage to the sensor diaphragm.
4. Level Transmitter Installation Precautions
( 1 ) Note that when you install wire level transmitter in the guide holes to avoid water port , plug and away from the surface , otherwise it will make the transmitter failure and damage.
( 2 ) the action should be let go gently , to prevent the momentum generated when placed between the media and the diaphragm , the diaphragm is damaged . Prohibited by hand or sharp implements poke holes and diaphragm pressure water , do not remove the head guide .
( 3 ) waterproof cable when using air conductivity Do not cut , to prevent media leaks to probe damage to the transmitter .
( 4 ) If there is no standard pressure source user , do not self-adjusting zero and span potentiometers.
( 5 ) In the case split level transmitter wiring should be done well sealed to prevent moisture and corrosive gases from entering .
( 6 ) should be used with protective casing in moving water or particulate media.
(7 ) the measurement medium is acid, alkali, oil , heat and other special media , please specify when ordering.
