Liquid Level Sensors

AST4500 / AST4510 - Submersible Pressure Transducer - The AST4500 and AST4510 submersible liquid level sensors are offered in pressure ranges starting at 1 PSI. Available with voltage and 4-20mA output signals, these submersible pressure transducers are an accurate and cost effective solution for monitoring liquids such as: water (canal, fresh, drinking, salt water holding tanks, etc.), diesel fuel, ballast water, oil, heating oil, and more. Each sensor is ABS certified for use on ships and intrinsically safe for Groups C and D.

AST44LP - Intrinsically Safe Low Pressure Transducer - With pressure ranges as low as 1 PSIG, the AST44LP offers the best price to performance ratio for tank level monitoring in the sensor industry. The AST44LP is also rated for instrinsically safe areas with installed with an approved barrier. With a compact size, this pressure transmitter can be mounted in compact areas, yet provide accurate measurements of liquids and gases.

AST4520 - Non-Clogging Level Sensor - Featuring a steel cage, all 316L SS and non-clogging diaphragm, the AST4520 level transmitter is designed for viscous media such as waste water level. Starting at 2.5 PSIG pressure ranges, the AST4520 can monitor the level of liquids for various media compatible with 316L and PVDF material. Each sensors is ABS certified for use on ships and intrinsically safe for Groups C and D.

AST5400 - Differential Pressure Transducer - For tank level sensing, the AST5400 can measure the level of sealed tanks by connecting to the top and bottom of the tank to calculate differential pressure. The AST5400 can offer high line pressure capability with low differential pressure measurements.

AST45PT - Liquid Level and Temperature Transmitter - For non-hazardous applications, AST offers the AST45PT liquid level and temperature transmitter for monitoring both liquid level and temperature from a single device. Monitoring temperature can be important to ensure that liquids to not freeze or boil or to calculate density at a given point in time.

AST5100 - Differential Pressure Transmitter - Low Pressure - Low Pressure - The AST5100 can be mounted as a gauge pressure transmitter or differential pressure transmitter for monitoring liquid level as low as 10 inches of water column.

AST4000 - OEM Pressure Sensors - When packaged with a sub-sea connector, the AST4000 can monitor level for deep sea applications up to 10,000 PSI.

AST5300 - Explosion Proof Differential Pressure Transmitter - Used in high line pressure (1500 PSI) applications, the AST5300 is an explosion proof and non-incendive rated differential pressure transducer with no liquid filled cavities and a high turndown ratio.
