Level Transmitter is lightweight and submersible.

AMETEK PMT Products May 14, 2004

Press Release Summary:

Model SDT indicates level of liquid by continuously measuring hydrostatic pressure via ion-implanted, silicon semiconductor sensor with integral Wheatstone Bridge circuit. Once sensor measures pressure, data is converted to 4-20 mA output signal, which may be sent to optional display meter. All electronics are mounted in submersible 316 stainless steel housing. Transducer is available calibrated for any span needed from 0-6 psi to 0-150 psi.

Ametek PMT Products Offers Low-Cost Submersible Level Transmitter

Model SDT Provides Reliable Light Weight Alternative

FEASTERVILLE, PA-AMETEK U.S. Gauge has added to its level measurement product line with the release of the Model SDT low-cost submersible level transducer. The Model SDT is specifically designed to provide the convenience of direct submergence in many types of liquid for quick, accurate and reliable level measurement.

The Model SDT provides a lower cost, lighter weight option for submersible applications. The simple design and rugged construction of this solid-state instrument provide long lasting service with virtually no maintenance.

The Model SDT transducer indicates the level of liquid by continuously measuring hydrostatic pressure via its sensing element, an ion implanted silicon semiconductor sensor with integral Wheatstone Bridge circuit.

Once the sensor measures the pressure, its data is converted to 4 to 20mA output signal (other outputs are available). This signal may be sent to an optional display meter, such as an AMETEK DMC Digital Meter Controller, for indication or control functions.

The Model SDT's design provides for excellent linearity and repeatability, low hysteresis and long-term stability. An optional temperature measurement capability also is available.

The Model SDT is easy to install. Simply lower the transducer into a vessel or well. All of the electronics are mounted in a submersible 316 stainless steel housing. A special cable support bracket is available. This provides extra stability to the transducer when used with long lengths of cable (up to 2500 feet) or when used in an agitated liquid.

The transducer is available calibrated for any span needed from 0 to 6 psi or 0 to 0.4 bar (0 to 14 feet or 0 to 4.2 meters of water) to 0 to 150 psi or 0 to 10 bar (0 to 345 feet or 0 to 105.4 meters of water). Lower pressure ranges also are available.

US Gauge has over 20 years of experience in piezoresistive sensor chip and stainless steel diaphragm technology and nearly 100 years of experience in pressure measurement. It has developed and perfected test methods and quality checks to ensure that every Model SDT transducer will operate for years within specification in tough and demanding environments.

AMETEK U.S. Gauge/PMT Products is a unit of AMETEK, Inc., a leading global manufacturer of electronic instruments and electric motors with annual sales of more than $1 billion.
