Instruction Manual

3/8

The Series 510 is designed to be self-supporting in any plane when rigidly mounted by the

pressure port (1/4” NPT process connection) under the removable nose cone. For rigid

installation, thread the transmitter in place using the wrench flats provided.

Both models are designed to be supported by the shielded electrical cable when suspension

mounted. A stainless steel strain wire is incorporated in the cable for attachment to a rigid

structure. If a rigid structure is not available, the SOR cable clamp accessory (P/N 9137-104,

ordered separately) provides a means for suspension without damaging the cable.

When mounting the transmitter, care must be taken to prevent the cable bending through a radius

smaller than 2 inches. Failure to observe this precaution may result in damage to the cable internal

vent tube. This may give incorrect readings from the transmitter. Care must be taken to prevent

water entering or foreign objects block ing the vent tube, either of which may result in a fault

condition. Faults of this nature are not covered by the warranty.

Avoid mounting the transmitter near a heat source which is liable to overheat the instrument

or cause a tempera ture gradient across it. If this is unavoidable, introduce a heat shield to deflect

radiated heat and thus maintain the transmitter at a uniform temperature within the specified limits.

Although the operating temperature of the transmitter extends to below 32°F, fluids must not be

allowed to freeze in the pressure port. Failure will occur due to the expansion of the frozen fluid in

the contained volume of the pressure port causing gross overpressurization. A failure of this nature

is not covered by warranty.

The transmitter should not be used as a step!

SOR 510 submersible products should not be used in liquids known to have

or possibly contain chemical compounds that react with butyl rubber or

stainless steel.

Installation

Before installing the transmitter, verify that the range stated on the transmitter label is

suitable for the level (pressure) to be measured.
