Mounting surface
|
Prepare a flat, rigid machine surface with a correct 1/4-18 NPT connection.
|
|
Torque
|
Do not exceed 45 N m (33 ft-lb) mounting torque.
|
|
Cable
|
Use the specified mating interconnect cable, maintain a 1.5 in minimum bend radius and secure the weatherproof boot and clamps.
|
|
Orientation
|
Mount in the measurement direction and verify polarity: pin A goes positive when case motion is toward the connector.
