They are used for the measurement of filling levels in tanks for liquid media where by an explosive atmosphere of category 1 (zone 0) exists in the gas space above the liquid and category 2 (zone 1) outside of the tank in the area of the connection box.

The hydrostatic probes are suitable for use in liquids - including aggressive types - in pressureless tanks. The hydrostatic pressure thereby acts on the membrane of the gauge head causing a change of an electric parameter. This change is converted by electronic analysis into a corresponding output signal.
The hydrostatic installed screwed sensors are used for filling level measurements in water and in clean to slightly contaminate liquids as well as in acids, alkaline solutions or aggressive media. Pressure less containers and tanks represent the application areas.
The hydrostatic dynamic pressure measurement are used for filling level measurements. Usable in pressure less container. The parts coming in contact with the media are made of PVC, PPH or PVDF.
DThe airing system is used for our hydrostatic probes of the HD-12... and HD-13... series with air connection. The bubbling of air is important to use the hydrostatic probes in fluids, which have the tendency to be come incrusted also for out gassing fluids .
The LU-150 is a short-range integrated ultrasonic level transmitter, intrinsically safe as Ex-version LU-180. This general purpose, 2 wire, 4 to 20 mA loop powered transmitter is ideal for liquids, slurries, and bulk materials in open or closed vessels to 5 m (16.4 ft). The transducer is available in PVDF copolymer, making the device suitable for use in a wide variety of applications. The LU-150/180 is easy to install and maintain, and can be quickly removed for cleaning as required by the food, beverage and pharmaceutical industries. The reliability of the level data is based on the Sonic Intelligence echo processing algorithms from Siemens. A filter discriminates between the true echo and false echoes from acoustic or electrical noises and agitator blades in motion. The ultrasonic pulse propagation time to the material and back is temperature-compensated and converted into distance for display, analog output. Key Applications: chemical storage vessels, filter beds, mud pits, liquid storage vessels, food applications Supplementary Components are designed to work with most types of instrumentation to provide enhanced functionality such as remote displays and remote monitoring solutions.
It`s a 2-wire loop powered ultrasonic transmitter for level, volume and flow monitoring of liquids in open channels, storage vessels and simple process vessels. Ideal for level monitoring in the water and wastewater industry and chemical storage vessels. The range of LU-sensors is 6 or 12 m (20 or 40 ft). Using Auto False-Echo Suppression for fixed obstruction avoidance, as well as an improved signal-to-noise ratio and improved accuracy of 0.15% of range or 6 mm (0.25"), the Probe LU provides unmatched reliability. The Sensorsincludes Sonic Intelligence® signal processing from the field-proven Probe and incorporates new echo processing features and the latest micro-processor and communications technology. The Probe LU offers communications with: HART . As well, for applications with varying material and process temperatures, the Probe LU incorporates an internal temperature sensor to compensate for temperature changes. Key Applications: chemical storage vessels, filter beds, liquid storage vessels.
The measuring transducer TK-101 and TK-101-Ex are built directly into the connection boxes of our Liquid Level Measuring Instruments of type TK-30_. The measuring transducer TK-101-Ex is also approved for use in explosive atmospheres Ex zone 0 (Cat. 1). For this purpose, the measuring transducer must be supplied with an intrinsically safe control circuit.
The TK-312 measuring transducer converts the resistance signal supplied from our TK-30... . continuous level sensors into a current signal proportionate to the level. The unit current signal (0/4...20mA) can be used for level indication, recording and control or other process variables present in three-wire circuits.
The TK-313 limit comparator can be used in conjunction with our TK-30... continuous level sensors with 0(4)...20 mA or 0...10 V output signal for level control / measurement. Where more than 2 limit values (change-over contacts) are required, individual limit comparators can be connected in parallel to form a functional unit or the evaluator TK-315 can be used.
The TK-315 limit comparator can be used in conjunction with our TK-30... continuous level sensors with 0(4)...20 mA or 0...10 V output signal for level control/measurement.
E.L.B. luminous row displays of type series TK-320...TK-322 are used for visually displaying process states such as filling levels. Through their design using strongly illuminating light-emitting diodes they are ideal for difficult applications, e.g. with light coloured surroundings. The luminous row permits a general view of the process state even from a distance.
The programmable digital display AD-31… can be used in all applications through the parameterization capability of the input values and the display area. The input circuit allows for direct connection of transmitters with voltage output (0(2)…+ 10 V, with current output 0(4)…20 mA or resistance remote transmitters, such as level measuring transmitters with resistance chains.
The TRM-100 turbidity measuring device is a compact device for measuring the turbidity of fluids. The “turbidity” is measured by using the scattered light method FNU (Formazine Nephelometric Units / 90° angle) for the turbidity range < 1.000 FNU - and by the transmitted light method FAU (Formazine Attenuation Units / 0° angle) for the turbidity range measure > 1.000 FAU.
The OAA-400-A1/A2 warning system serves to monitor oil, gasoline, lubricant or light fluid separator systems in areas subject to explosion hazards. Monitoring possibilities: Backwater: Monitoring of the maximum liquid level. Leak detection: In case of a dropping liquid level, as with a leak. Boundary layer: Monitoring of a defined oil layer thickness. Sludge level: Detection of sludge trap/ sand. The condition of connected sensors as well as their signal lines is monitored for line breakages and short circuits.
