Drexelbrook Impulse Series 2-wire Radar Level Transmitter
Drexelbrook Impulse TDR
Drexelbrook Impulse TDR

Drexelbrook has recently released a new 2-wire "Impulse" Guided Wave Radar (TDR) level measurement system.  The Impulse TDR is designed to measure the level, distance and volume of both liquids and slurries in either storage or process vessels. TDR (Time Domain Reflectometry) technology had been widely used for its inherent ability to remain unaffected by variations in the process materials electrical characteristics.   The key features of the Impulse TDR are:

  •  Push Button configuration via local display or HART communications
  •  Up to 50 ft. measurement range
  •  No calibration required and no need to move the level in the vessel to start-up
  •  Dual compartment housing separates wiring terminals from the electronics/display
  •  Class I, Div 1, Zone 0 classification
  •  Suitable for both liquids and slurries
  •  3 Sensor types (single or dual element and coaxial sensors) up to 392 F and 580 psig
  •  Measurement of low dielectric materials down to 1.4
  •  Unaffected by changes in density and dielectric properties, dusts, vapors and turbulence

Easy to use and easy to set-up, you will have the level measurement you need, configured within minutes.   Please contact your local Gilson Sales Engineer to arrange a demonstration of the Impulse TDR and to look at any tank applications in your plant.

Multi-Channel Analyzer with Wireless Communications

The Insite Instrumentation Group PT2 multi-channel analyzer is a unique system that combines advanced electronics with the latest in sensor technology. The analyzer will wirelessly communicate with up to 16 sensors and accepts any combination of DO, SS, pH, or ORP sensors The system allows for flexible and economical process monitoring and control. The system will result in significant cost savings during installation due to no wiring and conduit runs between the analyzer and sensors.

Insite wireless transmitter
Insite Transmitter

The Insite IG wireless self-healing mesh network is a multihop system in which sensor transmitters assist each other in transmitting packets through the network, especially in adverse conditions. You can drop these networks into place with minimal preparation, and they provide a reliable, flexible system that can be extended to 16 devices.

The wireless mesh network topology for industrial control and sensing is a point-to-point-to-point, or peer-to-peer, system called an ad hoc, multihop network. A node can send and receive messages, and in a mesh network, a node also functions as a router and can relay messages for its neighbors. Through the relaying process, a packet of wireless data will find its way to its destination, passing through intermediate nodes with reliable communication links

Wireless mesh network

In a mesh network, you can shorten the distance between nodes, which dramatically increases the link quality. If you reduce the distance by a factor of two, the resulting signal is at least four times more powerful at the receiver. This makes links more reliable without increasing transmitter power in individual nodes. In a mesh network, you can extend the reach, add redundancy, and improve the general reliability of the network simply by adding more nodes.

Like the Internet and other peer-to-peer router-based networks, a mesh network offers multiple redundant communications paths throughout the network. If one link fails for any reason (including the introduction of strong RF interference), the network automatically routes messages through alternate paths.

Employe Profile,  Lauren Schultz
LAS photo

This edition, we would like to introduce you to Lauren Schultz.  She is a valued member of our Inside Sales team here at Gilson and has been with us since 2006. She works as an Inside Sales Assistant with two of our engineers, Dave Snyder and Kendra Mitchell.  She graduated from Clarion University of Pennsylvania, with a BA in English, and started with Gilson Engineering shortly after graduation.

Although she has a degree in English, she has worked hard to learn the ropes of technical sales.  She enters orders and creates quotes for Dave and Kendra's accounts along with following deliveries, scheduling repair paperwork, and handling customer phone calls.  Lauren is a hard worker, who is willing to help where she can.  With each job, she feels that she is able to learn more allowing her to be more supportive to her customers in the future.

In her spare time, Lauren is very dedicated to the Multiple Sclerosis Society.  Each year, she leads a team at the Pittsburgh MS Walk and works to raise money for her cause.  This past year, her team consisted of over sixty-five members including family, friends, and co-workers who raised just under $5,500 to help find a cure.  She is thankful to all that help her with her efforts and is looking forward to next year's walk.

Tech Quiz Answer
Answer: B, Conductivity
In most magmeters, as long as the fluid conductivity is above 5 microsiemens (micromho/cm) the magmeter will work.  The magmeter measures volumetric flow.
