Turn to the Yokogawa YS1700 to Replace Discontinued Siemens 353 SLC Controllers

Siemens 353 is discontinued.

The very popular Siemens 353 SLC controller was discontinued, leaving many process users high and dry for a suitable replacement. We're glad to announce that there is a great alternative - the Yokogawa YS1700 PID loop controller.

Yokogawa YS1700
is a drop-in replacement.

The YS1700 is a drop-in SLC replacement for the Siemens 353 and is an ideal choice for many control applications offering extreme reliability and sophisticated control. This product family has bright, easy-to-read displays, multiple I/O points, and powerful loop tuning. For critical applications, the YS1700 employs dual CPUs for maximum reliability and hard-manual control for added protection.

Yokogawa Pressure Transmitter Local Parameter Setting (LPS) Tutorial

We have all run into this scenario one time or another; you're out in the field when you realized you need to make an adjustment to one of your Yokogawa pressure transmitters, but your Hand Held Communicator (HHC) is back at the instrument shop.

If you have a Yokogawa EJA-E or EJX-A series pressure transmitter it is not a problem. Yokogawa's Local Parameter Setting (LPS) gives you easy access to nine (9) basic parameters:

1. Tag Number
2. Unit of measure
3. Set LRV (4 mA)
4. Set URV (20 mA)
5. Damping Time
6. Transfer Function (Linear or Square Root)
7. Display
8. Calibrate LRV (Requires applied pressure)
9. Calibrate URV (Requires applied pressure)

LPS is available on any EJA-E or EJX-A series model with HART (Output Signal code -E or -J) and BRAIN (Output Signal code-D) communication.

LPS requires Integral Indicator with Switch (code E). The LPS utilizes the Range-setting Switch on the indicator and the Zero Adjust Screw to work through the menu and change values.

The video below provides a detailed tutorial on how to use Yokogawa LPS.

New Product Alert: 2-wire HART 7 Temperature Transmitter

PR Electronics PR 5437

PR Electronics, a manufacturer of analog and digital signal conditioning modules for application in industrial control and factory automation, recently introduced it's PR 5437 2-wire HART temperature transmitter.

The new PR 5437 allows customers to protect high-integrity process measurements, e.g. in flare stacks or reactors, with an automatic backup in the event of primary sensor failure, while continuously checking on the validity of process values. It also provides the best accuracy, stability and reliability across a wider ambient temperature range of -50°C to +85°C.

Additionally, sensor redundancy and drift detection ensure maximum uptime and process validity, while NAMUR NE107 compliance makes for easier process diagnostics and preventative maintenance scheduling. A full IEC 61508-2010 functional safety assessment up to SIL 3 means that the PR 5437 can also be trusted to perform in the most critical safety applications.

Coriolis Mass Flow Meters

Coriolis Mass Flow Meter (Yokogawa)

A Coriolis mass flow meter consists of a U-shaped tube that deflects or vibrates as the fluid flows through it. The operation of this type of mass flow meter is based on the conservation of angular momentum as it applies to the Coriolis acceleration of a fluid. Coriolis acceleration is that tangential force experienced when one walks radially outward on a rotating platform. The force is only experienced when one changes position in relation to the center of rotation.

Operating Principle

As fluid enters the U-shaped tube, it is forced to take on the vertical movement of the vibrating tube. When the tube is moving upward, the fluid flowing into the meter resists being forced up by pushing down on the tube. Having been forced upward, the fluid flowing out of the meter resists having its vertical motion decreased by pushing up on the tube. The two opposing forces on the tube cause it to twist. The amount of twist is directly proportional to the mass rate of fluid flowing through the tube.

Major Components and Operation

A mass flow meter consists of a vibrating U-shaped tube in which the Coriolis acceleration is created and measured. In place of the rotational motion described above, the inlet and outlet of the tube are held fixed while the tube is vibrated sinusoidally about an axis formed between the inlet and outlet, typically by a magnetic device located in the bend. In most devices, magnetic sensors located on each side of the flow tube measure the respective velocities, which change as the tube twists. Newer models have two U-shaped tubes to measure fluid flow.

Coriolis mass flow meters are generally used in the following liquid applications: harsh chemicals, low to medium viscosity, foods, slurries, and blending systems. Gas applications are somewhat limited since the density of low-pressure gases is usually too low to accurately operate the flow meter. Typically, thin walled tubes are used for gas applications. However, when applicable, the mass flow meter eliminates the need for pressure and temperature compensation and the hardware necessary to implement these functions.
