Honeywell’s Process Instrument Explorer (PIE) configuration software used for configuring UDC controllers and the UDA analytical controller communicates with the instruments via RS-485, Ethernet, or Infrared (IR).
Since most newer PCs don’t ship with built-in serial ports to connect an IR adapter, you can use a USB-to-RS-232 converter, and then connect using the Actisys serial-to-infrared adapter (ACT-IR220L+). The USB converter will plug directly into your PC’s USB port, but install on a virtual COM port.
Here’s where it gets tricky: That COM port has to match the COM port used in PIE, and PIE doesn’t support ports above COM8.
Chemical seals and fills are often necessary to protect your process instrumentation from harm. But the wait for a custom gauge-and-seal, switch-and-seal, or transmitter-and-seal combination could be an issue, keeping your process offline for longer than necessary, or costing a premium for quick delivery.
We’ve removed the potential for downtime and rush charges with our WIKA-certified assembly station, and improved stock of most popular transmitters, switches, gauges, diaphragm seals, and fill fluids. Lesman customers can experience next-day delivery on custom assemblies from in-stock instrumentation.

Traditionally, combustion control panels have been living in a hard-wired world. More often than not, the status of a burner system is communicated by indicator lights on a Flame Safeguard (FSG) terminal.
With the increased use of Programmable Logic Controllers (PLCs) controlling all aspects of a combustion system, customers are demanding more information from the FSG, as many operators manage their systems from a centralized control room.
While some customers have traded in their indicator lights for relays with dry contacts that feed back into their PLC, other customers are looking to simplify the communication between the FSG and PLC, while extracting more information on the operation of their burner system.
Here, we will go over some examples of technologies that are available today, and how you can get the information you need to where you need it.
In case you missed May’s webinar with Sartorius Intec on load cells, we’ve put together some of the key points:
Let’s start with the most common weighing element: the strain gauge load cell.
A strain gauge load cell can be found in bench platforms, floor scales, and in some cases, tank and hopper systems. It is the most common load cell used in the weighing industry.
The most common electrical strain gauges are thin, rectangular strips of foil with maze-like wiring patterns on them, leading to a couple of electrical cables. You stick the foil onto the material you are measuring and wire the cables up to your computer or monitoring circuit.
Custody transfer flow meters are used to determine how much of a commodity changes hands in exchange for some monetary, financial or other recognized trade consideration.
All custody transfer applications involve at least one buyer and one seller. During custody transfer, accuracy is of great importance to both the company delivering the material and the recipient.
In order to ensure reliable and accurate measurement, devices are certified for custody transfer by a nationally recognized body. For Coriolis flow sensors, custody transfer approvals are mandated by the US National Conference on Weights and Measures office.
