SITRANS LR560 2-wire, 78 GHz FMCW radar level transmitter for continuous monitoring of solids in silos to a range of 100 m (328 ft).

SITRANS LR560’s plug and play performance is ideal for most solids applications, including those with extreme dust and high temperatures to +200 ºC (+392 ºF). Unique design allows safe and simple programming using the Intrinsically Safe handheld programmer without having to open the instrument’s lid.

The SITRANS LG series are guided wave radar transmitters for level, level/interface, and volume measurement of liquids and solids. It is unaffected by changes in process conditions, high temperatures and pressures, and steam.

The SITRANS LG series comes in four different models,
depending on the applications, level of performance, and functionality required:

  • SITRANS LG240 offers configuration options for your hygienic application requirements
  • SITRANS LG250 Highly flexible solution for liquid level and interface applications. Extremely versatile offering solutions for storage, separation of materials or difficult ammonia applications

  • SITRANS LG260 Ideal for measuring level in medium range solids applications including; grains, plastics, and cement

  • SITRANS LG270 offers configuration options for extreme conditions including high temperature and high pressure applications such as: harsh applications found in chemical, HPI and energy industries for example, LPG gas tanks, steam boilers and distillation columns

The IMP from Pulsar is non-contacting ultrasonic level measurement without compromise. The all-in-one self-contained units have the benefit of digital echo processing specially designed for IMP. IMP can be programmed via the integral keypad or using IMP PC, IMP’s specially designed software.

IMP is available in 3m, 6m and 10m versions, and each unit is configurable either as a 2 or 3 wire device.

IMP is also available as an Intrinsically Safe (I.S.) unit, with a distinctive black cap instead of green, meeting ATEX EEx ia IIC T4 and IECEx.

Pulsar’s innovative dB range of transducers has taken ultrasonic level measurement into a new era. Unlike the high voltage, frequency dependent transducers of other manufacturers, which require special, protected interconnect cables, or low powered transducers built with intrinsic safety rather than performance in mind, the dB series combines low electrical power that meets intrinsic safety requirements with extraordinary high sonic power to give range and performance. Short blanking distances and narrow beam angles improve performance, especially when the signals are being analysed by Pulsar’s DATEM software
Deceptively simple, the Pulsar blackbox range includes all the echo processing sophistication of the Pulsar Ultra range, but in basic form without the display and on-board programming capabilities that are unnecessary in a distributed control environment.The blackbox units can be teamed with any of the dB transducers, making a 125mm to 40m measurement ranges available
The Pulsar Ultra 3
The Pulsar Ultra 5
The Pulsar Ultra 3 and 5 represents the leading edge of ultrasonic level measurement and control. Sophisticated, full function controllers with either 3 (Ultra 3) or 5 (Ultra 5) control/alarm relays. With wall, fascia, panel or rack mount, Ultra 3 and 5 units provide large displays with intuitive and straightforward menu programming. An Ultra system consists of a control unit and a transducer, which may be positioned up to 500 metres away. Both Ultra 3 and Ultra 5 have the option of bus type digital communications and data logging, coupled with the dB series of transducers measurement ranges from as little as 75mm right through to 40metres on solids or liquids are available.

The Siemens SITRANS Probe LU is a 2-wire loop powered ultrasonic transmitter for level, volume and flow monitoring of liquids in storage vessels, simple process vessels and in open channel flow measurement. The operating range of the Siemens SITRANS Probe LU is either 6 or 12 meters and the unit is also equipped with Auto False-Echo Suppression for fixed obstruction avoidance. The Probe LU offers two communications options, HART or PROFIBUS PA (Profile version 3.0, Class B)
The Siemens MultiRanger is a versatile short to medium-range ultrasonic single and multi-vessel level monitor/controller for virtually any application in a wide range of industries. MultiRanger can be used on different materials, including fuel oil, municipal waste, acids, and woodchips or on materials with high angles of repose. The Siemens MultiRanger offers true dual point monitoring, digital communications with built-in Modbus RTU via RS-485, as well as compatibility with SIMATIC PDM, allowing PC configuration and setup.
The SITRANS LC300 is an inverse frequency shift capacitance continuous level transmitter for liquids and solids applications. It is ideal for standard industrial applications in chemical, hydrocarbon processing, food and beverage and mining, aggregate and cement industries. SITRANS LC300 is a 2-wire level measurement instrument combining a sophisticated, yet easy-to-adjust microprocessor with field-proven probes. It is available in two versions: rod and cable. SITRANS LC300 has a stainless steel process connection with PFA-lined probe. Materials with low or high dielectric properties are accurately measured and Active-Shield technology helps in ignoring the effects of buildup near vessel nozzle
The Scientific Instruments Inc. Model 6290 Tank Gauging System is capable of providing automatic continuous level gauging, temperature monitoring, and density measurement of liquid media. These measurements are achieved by means of a PC-based control unit and an electromechanical drive mechanism, which operates as a unit to position a multi-sensor probe assembly suspended within the liquid storage tank. The system can accommodate LNG, propane, butane, ethane, or any similar cryogenic media. The probe is moved vertically by the drive mechanism in response to commands generated by the control unit. Both automatic and manual control of the probe assembly is incorporated into the system design. All system components, which are located inside the tank, can be completely removed from the tank for inspection and/or maintenance at any time. Probe position, temperature and density readings are displayed continuously to the operator at the control unit via an alphanumeric display.
