Promass Q 300 provides the highest measurement accuracy for mass flow, volume flow and density. Being the preferred choice for custody transfer applications, it has also been optimized for liquid applications where entrained gas is known to be present.
The compact transmitter offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. Heartbeat Technology ensures compliance and process safety at all times.
Our Bulletin 6200 VersaView® 5400 industrial computers feature an open architecture, which provides greater application flexibility. These computers have a quad core Intel Atom E3845 processor and a 128 GB solid-state drive.
The units are available with or without integrated display. Display versions have a modern, edgeless glass design with ten-point, capacitive multi-touch screen.
A Control Design reader asks: I'm a recent college graduate and controls engineer at a system integrator who specializes in remote monitoring and process skid design, so I'm constantly selecting control enclosures for a variety of applications from office-like environments to outdoors in the rain and hot sun. I'm trying to standardize on a single enclosure type, but that doesn't seem possible. While stainless steal is great, it is expensive, and, while plastic works well, I find cracks or holes smashed in the doors of the enclosures at remote sites.
Obviously, the size of the enclosure is important, but what are some other considerations when selecting an enclosure, and what are some common mistakes I should watch out for? I don't want to purchase 100 enclosures that crack, melt, rust or otherwise are not suitable for the application. What do you think? Just get a battleship gray, NEMA 12 enclosure and hope for the best?
When your industrial motor requirements move beyond a single-speed application to a variable-speed application with adjustable acceleration and deceleration, and possibly precision position or torque control, the motor and drive need to team up for a winning solution.
The motor drives connect to and provide enhanced operation to dozens of different types of motors. These include dc, ac, stepper and servo motors. There are definitions to be found online along with the advantages and disadvantages of each type of motor. However, a big thing to keep in mind is that many of the motors are designed for a specific application or their applications are limited.
There are also many characteristics to know when it comes to motor selection. This includes things such as when a dc motor’s speed is high, its torque is low and vise versa. Another characteristic is that running an ac motor slower using a variable frequency drive (VFD) is a common way to save energy when operating fans, pumps or similar devices. Another is that the stepper motor typically has maximum torque at zero speed, and the servo motor is known for its dynamic speed control and precision position and torque control.
Starting and stopping a motor can be done with three common methods: a motor starter, soft start or variable frequency drive (VFD). As of late, the use of a VFD is becoming more popular than ever due to its claimed efficiency benefits, but be sure it is needed. And, once specified, it must be properly installed to ensure reliable operation.
To start, take a step back and be sure you need a VFD for the application, as many users don't realize real benefits. Do you need to vary the speed of the motor or change the motor's acceleration? If neither, a motor starter is simple and will work great. Just want to soften the motor starts? Consider a soft starter. For all the above, a VFD may be the best choice.
The VFD, often called an ac drive or inverter, takes a single- or three-phase signal and varies the speed of a three-phase ac induction motor. This is its main benefit. Running a motor more slowly can save significant energy, and speed changes may be useful to the application. Another big benefit is adjustable acceleration and deceleration. Less acceleration can soften the mechanical forces at motor start and reduce inrush current. The VFD also has built-in overload protection and motor start/stop control functions.
Introducing the CompactLogix™ 5480 Controller, available in 2017.
Our Bulletin 5069 CompactLogix 5480 controllers are real-time controllers with Windows 10 IoT Enterprise running in parallel to the Logix control engine. The CompactLogix 5480 uses the same re-architected control engine deployed in the ControlLogix® 5580 and CompactLogix 5380 controllers. This line of Logix controllers supports embedded Windows applications, such as analytics, data gathering, and predictive computations.
