NIVELCO EasyTREK SP-500 Series Level Transmitters

The newest generation EasyTREK SP-500 series level transmitters are based on NIVELCO’s 35 years of experience with ultrasonic level measurement. The IP68 rated units have their transducer and processing electronics incorporated in one single housing. The new EasyTREK transmitters utilize HART® 7 communication so they can be used in multidrop systems connected to MultiCONT process controller/display, or to a PC with the help of the UNICOMM HART®-USB modem or similar. The transmitters can be remotely programmed also with Handheld Field Communicator, and can be connected wirelessly to a PC with the SAT-504 Bluetooth® HART® modem.

The ultrasonic level metering technology is based on the principle of measuring the time required for the ultrasound pulses to cover the distance from the sensor to the level to be measured and back. The echoes bounced back from the surface of the medium to be measured reach the sensor surface after the time of flight of the ultrasonic impulse. The time of flight of the reflected signal is measured and processed by the electronics, and then this is converted to distance, level, volume or flow proportional data using the customizable tank dimensions or the pre-programmed flume / weir parameters.

7 Steps for Selecting the Right Industrial Gas Detection Solution

Abstracted from the Honeywell Analytics article titled "How to Select the Right Gas Detection Solution" by Don Galman

Step 1 - Know Your Site Risks

7 Steps for Selecting the Right Industrial Gas Detection SolutionBefore beginning to consider gas detection equipment, a risk assessment needs to be conducted. Any company employing staff has the obligation to conduct risk assessments to identify potential hazards and these can include potential gas, vapor or Oxygen deficiency risks. If gas hazards are identified, gas detection is applicable as a risk reduction method.

Step 2 - Know and Identify the Primary Objective

Depending on the processes being undertaken and the gases being detected, remote or off-site alarm notification plus event data logging/reporting may also be required for Health and Safety management records. Another factor impacting on the need for enhanced reporting functions might be regulatory compliance or a condition of insurance.

Step 3 - Be Thorough and Ask the Right Questions

Having identified the primary objective, the suitable equipment is selected by asking a number of key questions. These fall into three broad categories:

  • The gases to be detected and where they may come from
  • The location and environmental conditions where detection is to take place
  • The ease of use for operators and routine servicing personnel

Step 4 - Identify the Gases to be Detected and Where They May Come From

The gases to be detected should be identified by the risk assessment, however experienced gas detection equipment manufacturers and their approved distributors are often able to help in this process, based on their experience of similar applications. However, it is important to remember that it is the end-user’s responsibility to identify all potential hazards.

It is also essential to identify the potential source of a gas release as this helps determine the number and location of detectors required for a fixed gas detection system.

Step 5 - Understand the Operating Environment

The performance, accuracy and reliability of any gas detection equipment will be affected by the environmental conditions it is subjected to. Temperature, humidity and pressure levels at the location all have a direct bearing on the type of equipment that should be selected. Additional factors such as potential variations resulting from a production process itself, diurnal/nocturnal fluctuations and seasonal changes may also affect the type of device which is suitable.

Step 6 - Understand How the Product Functions

The next area of consideration relates to additional product functionality. Aspects like wiring configuration are important, especially when retro-fitting into an existing application. If the apparatus is being integrated into a separate safety system, certain communication protocols may also be required such as HART®, Lonworks or Modbus®.

Consideration will also need to be given regarding the requirement for local displays on transmitter units and local configuration of the unit and gas displays may also be a useful addition.

Step 7 - Ease of Use

Routine maintenance is another important consideration. Some gases and vapors can be detected with a number of different sensing technologies, e.g. Hydrocarbon gases with catalytic beads or Non-dispersive Infrared NDIR. Catalytic beads do not provide fail-to-safety operation and therefore can require a high frequency of routine maintenance, however NDIR based solutions tend to have a higher initial purchase price, but may require less routine maintenance. In-house resource to undertake such routine maintenance needs to be identified and in the absence of such a resource, budgeting for third party maintenance is an important factor in selecting the right equipment.


There are many gas detection products on the market that might appear to be the same, but a closer inspection of specification, functionality and features reveals major differences in what products can do and the potential value they can offer. Similarly, individual applications are also unique in their respective designs, needs and processes undertaken.

New Product Alert: BLH Nobel 1756 WM Dual-channel Plug-in Weighing Module for the Rockwell 1756 ControlLogix Chassis

The BLH 1756-WM is a weighing module designed to directly plug into the Allen-Bradley 1756 ControlLogix chassis.

Intended for inventory measurement and process control, the 1756-WM offers users simple configuration and is suitable for tank, silo, vessel and hopper weighing in the United States and Canadian markets.

The weighing module seamlessly integrates weighing into the Allen-Bradley PLC by directly fitting into a single slot in the 1756 ControlLogix chassis via a screw connection plug. The weighing module is powered from the input/output chassis backplane and needs only the load cells for connection.

Once in place and set-up, calibration and configuration for the 1756-WM are simply achieved through the Rockwell RSLogix 5000® PLC Development Software; no other external configuration utilities are required. Dual independent strain gage inputs—with sense inputs for six-wire connection—power up to eight 350-ohm load cells with up to four parallel 350-ohm load cells per channel.

Condition Monitoring Systems Provide Improved Performance, Safety & Profits: A Video Presentation

From large turbine generator protection to general-purpose equipment, rotating machinery provides critical and non-critical functions in plants across many industries in the USA. To avoid unnecessary downtime, plant operators turn to condition monitoring systems to monitor the health of these machines. Vibration is one of several important parameters that may lead to the early detection of machine trouble. Operators can benefit from efficient maintenance and avoid unscheduled downtime by performing periodic or constant monitoring of vibration.

The video below provides a quick overview of the performance, maintenance, safety, and profitability benefits that condition monitoring systems provide to plants who implement their use.
