Industrial settings can present difficult or unique challenges to automation and control designers. Each new challenge seems to be met with a new, improved, or adapted product which fulfills the requirements.

Analynk's standard array of wireless transmitters operate on 24 Vdc. For installations without any appropriate power source, three models are configured to operate on power provided by batteries. The A753-BT transmitters operate on battery power, utilizing a real time clock to schedule transmission intervals appropriate for the application. The transmitter also provides an excitation voltage for external devices. Your sensor's 4-20 mA output provides input to the Analynk transmitter, along with two discrete switches. The transmitter communicates with all of Analynk's receivers.

The unit pictured is configured for use in a hazardous area, with explosion proof enclosure. Other models are suitable for DIN rail mounting in an enclosure of your selection, or provided preconfigured in a NEMA 4 enclosure.

Explosion Proof Antennas For Wireless Communications in Hazardous Industrial Settings

CTX Series Explosion Proof Antenna
Analynk

Wireless connections between process measuring and control devices brings several benefits to an industrial operation. The signal cable free installation saves valuable time and space, reduces damage exposure, and simplifies process equipment layout modifications.

Implementing wireless communications in hazardous areas, whether through WiFi or other radio frequency channels, poses a unique set of challenges to successful implementation. Points of network access and other transmission and receiving equipment will require a level of isolation and hardening appropriate for the hazardous industrial environment. Specialized explosion proof enclosures can house the needed equipment, but antennas must extend outside these metal enclosures and into the hazardous environment in order to transmit and receive process signals. This imposes rigorous requirements on antenna design and construction.

Analynk Wireless manufactures patented UL listed hazardous area explosion proof antennas for industrial installations.  Their CTX and CTM series antennas carry an array of third party approvals and are suitable for use in a broad range of hazardous environments. Models can accommodate WiFi and other RF communications across frequency bands commonly utilized in industrial settings, as well as cellular and satellite communications.

Data sheets for the CTX and CTM Series antennas are included below for more detail. Share your wireless communication challenges and application questions with the experts at Analynk and work together to produce the best solutions.

Flow Control of Slurries and Liquids With Entrained and Suspended Solids

Industrial process control can involve the manufacture, storage, or transport of almost any imaginable fluid. Media can range from water to concrete, hydrogen gas to steam, and anything in between or outside of those boundaries. Valves are a favored control device for regulating fluid flow and they are available in uncountable varieties, each with particular aspects making them more or less suitable for a particular media or application.

Most industrial valves consist of a body, a stem, and some form of flow obstruction which is located within the media flow path. Operation of the stem repositions the obstruction to allow or block the flow. All of these valve types have a defined sealing surface where the obstruction contacts the body. They also have additional seals where the stem penetrates the body. These design features, while providing certain functions and application advantages, also add to the operational complexity and parts count for the valve.

There is a valve type with a simple operating principle that provides superior performance when the application involves certain media characteristics. It is called a pinch valve, and here is where it excels.

• Resistance to abrasion and corrosion from slurries or fluids containing suspended solids and the ability to provide tight shutoff around particulates
• Media and environmental temperature range -40 deg F to +300 deg F
• Low to moderate operating pressure
• Flow regulating capability and tight shutoff
• Non clogging
• Straight through full bore design with minimal flow resistance
• Isolation of the valve body and workings from the media
• Low parts count, low maintenance, easy repair/replacement

A pinch valve consists of a sleeve, through which fluid flows, and a means to compress or "pinch" the sleeve to reduce the open area inside the sleeve. The sleeves are most often fabricated from elastomers with various types of fiber reinforcement. Closure is commonly achieved through movement of one or two bars to squeeze the sleeve, providing throttling or positive closure. The flexibility of the sleeve material allows for tight shutoff, even with fluids containing suspended solids. The valves can be coupled with electric or pneumatic actuators and are available with industry standard connections. One valve variant has a body that can be pressurized to close the sleeve, without the need for a separate actuator. Pinch valves are available with and without an enclosing body.

You should be familiar with the capabilities and forms of this unique valve type. When confronted with certain application challenges, a pinch valve can be a superior solution.

Analynk is committed to excellence in process control, providing wireless communications for process signals, as well as explosion proof enclosures for wireless access points.

Signal Alarms for Process and Operations Monitoring

Telmar 500 Series Signal Alarm
Analynk

Signal alarms provide functionality related to a monitored process condition, which serves as the input to the device. High, low, or both high and low alarm points can be set on the device. When the process condition reaches one of the setpoints, a relay changes state. The relay, rated at 5.0 amperes at 120 VAC, can be used to annunciate the alarm occurrence or activate another device to take some other appropriate action. A number of input options are available that accommodate a broad range of process applications.

• Thermocouple
• Millivolt DC
• RTD
• AC or DC Current
• Slide Wire
• Strain Gauge
• Tachometer
• AC or DC Voltage

The standalone signal alarms can be incorporated into new control installations, or added to existing control systems to expand functionality. More information can be found in the data sheet included below, or reach out to Analynk and share your signal or process monitoring challenges and requirements.
