The U5700 submersible
pressure transducers from the UltraStable line of
MEAS, with their modular design, include an IP68 rated connection and
submersible polyurethane jacketed cable along with a variety of pressure
port options. This latest series features high accuracy and a quick
turnaround for demanding commercial and heavy industrial applications,
as well as liquid level applications. This series is suitable for
measurement of liquid or gas pressure, even for difficult media such as
contaminated water, steam, and mildly corrosive fluids.
The transducer’s
durability is excellent with no O-rings or organics
exposed to the pressure media. The transducer can be fully submerged
since the wetted materials for the back end consist of FKM
Fluoroelastomers,
316 stainless steel and polyurethane. A POM
protective cap port option is also available for liquid level applications.
The U5700 is weatherproof and exceeds the latest heavy industrial CE
requirements including surge protection. The circuit is protected from
reverse wiring at input and short circuit at output.
This product is geared to the OEM customer for low to mid volumes.
MEAS stands ready to provide a custom design of the U5700 where the
volume and application warrants. Additional configurations not listed are
either available or possible. Please inquire for further information.

Notes
Compensated Temperature: The temperature range over which the product will produce an output proportional to pressure within the specified
performance limits.
Usage Temperature: The temperature range over which the product will maintain the IP68 rating.
Storage Temperature: The temperature range over which the product can be stored safely in occasions without pressure applied or power
input and remains rated performance. Beyond this temperature range may cause permanent damage to the product.
All configurations are built with voltage reverse and output short-circuit protections.

Notes:
1. The drain wire is internally terminated to pressure port.
2. A psiG transducer requires a vent to atmosphere on the pressure reference. This is accomplished via a vent tube in the cable.
The end of the cable should be terminated to a clean dry area.
3. The IP68 rating is only met when the cable termination is to a dry clean area. Moisture can enter the transducer through the
vent tube at the cable termination.
