ABB Level LMT100-2 Floats

Overview

The LMT100 is based upon the magnetostrictive principle. 1. The device electronics generates a low energy current pulse at fixed intervals. 2. The electrical pulses create a magnetic field which travels down a specialized wire inside the sensor tube. 3. The interaction of the magnetic field around the wire and the magnetic float causes a torsional stress wave to be induced in the wire. This torsion propagates along the wire at a known velocity, from the position of the magnetic float and toward both ends of the wire. 4. A patented sensing element placed in the transmitter assembly converts the received mechanical torsion into an electrical return pulse. 5. The microprocessor-based electronics measures the elapsed time between the start and return pulses (Time of Flight) and converts it into a position measure- ment which is proportional to the level of the float. LMT100 is preferred for: • Interface Measurement • Exceptional performance with emulsion • Measurement with foam on layers fluid surface • Hydrocarbons and chemical control Features:

ABB Level LST400 Ultrasonic

Overview

The transmitter’s microprocessor simultaneously fires an electronic pulse to the transducer and starts a timer. The transducer converts this electronic pulse to an acoustic pulse, which is directed toward the surface of the material being measured. When the acoustic pulse contacts the surface of the material, energy is reflected back to the transducer, which converts this reflected energy back to an electronic pulse. This pulse is sent back to the microprocessor, which stops the timer and determines the “time of flight” of the signal. By combining the speed of sound through air and the “time of flight” of the pulse, the microprocessor accurately determines the level of the product. Powerful software removes false echoes from the signal and electronic filters remove ambient noise.

ABB LMS200 in KM26

Overview

The LMS200 consists of two snap action switches operated by a precision actuation mechanism. The actuation mechanism consists of two cams arranged on a spindle assembly. A rod magnet is internally mounted to a spindle assembly in such a way as to cause the spindle to rotate when a magnetic field of proper orientation passes near the switch. A magnetic KM26 float passing by the LMS200 in either the upward or downward direction will cause the switch to change states. After the float has passed, the switch will remain in its respective state until the float passes the switch going in the opposite direction. The action of the switch is break before make. The unique magnetic coupling action eliminates the need for seals, diaphragms, springs, or torque tubes. There is no physical contact between the switch and the process. Magnetic coupling also eliminates the necessity of process connections and insures total isolation from the process.

Data

  • 10 amps rated DPDT switch (NO or NC contacts)
  • Unique concept of magnetic coupling, eliminating direct contact with process
  • No process piping or valves required
  • Easy mounting and adjustment; only small screwdriver required
  • Trip point infinitely adjustable without changing process piping
  • Vibration resistant
  • Compact design
  • Suitable for high temperature applications
  • Industrial Explosion Proof IP66/67 and NEMA4X enclosure with ATEX/IECEx, FM US and Canadian approvals

How do I determine which instruments I need and their cost?

This depends on what you are needing to control or measure, your operating environment, your specific process flow, and many other factors. Durkin’s process specialists can help you determine the specific process instruments (down to the part number) that suit your application, budget, and expected life-span the best. Call (314) 432-2040 or contact us.

What is process instrumentation?

Process Instrumentation are sensors and instruments used to measure and control process variables including levels, flow, pressure, temperature, pH, and humidity.

In-field instruments, such as flowmeters or temperature sensors, are close to the process or measurement point, or may even have process liquids flowing through them. Panel instruments not usually where the process is happening, but are rather located ina controlled room or with the line controls.

Common types of process instrumentation include: flow meters, rotometers, level sensors, temperature sensors, recorders (to record process data), actuators, valves, gas analyzers, positioners, and actuators.

What symbols are used for process instruments?

Depending on the program, plant standards, and engineering firm that did the drawings, symbols for process instrumentation can vary. You should have been supplied with a lead or legend sheet that defines the symbols for the particular set of drawings you are looking at. However, there are a common set of generally agreed upon symbols, examples of which you can reference here.

Robert Cook at AiCHe has put out an excellent blog post on interpreting and using instrumentation symbols. If that doesn’t help, contact Durkin and one of our team members can help you solve the mystery: (314) 432-2040

Do you only supply the brands listed?

We carry a wide-range of process instrumentation and solutions. You can see our full supplier list here, but we may be able to source brands or point you the right distributor for other brands. More importantly, we can help you determine the appropriate instrumentation and controls solutions needed to solve your process issues. Talk to one of our experts today: (314) 432-2040 or fill out a contact form.
