The field unit is an integrated input module, signal conditioner and RF transceiver with self-contained power operating in the 902 MHz to 928 MHz ISM license-free band.

	Switch-Input Field Unit The Switch-Input Field Unit is ideal for determining the state of contact switches without running wiring in the field.

	Acoustic Field Unit The Acoustic Field Unit is non-invasive and monitors ultrasound in the 40 kHz frequency range. The Acoustic Monitor Field Unit is ideal for monitoring pressure relief valves, steam traps, automatic tank cleaning (CIP) systems and other applications that generate ultrasound. It can also monitor on/off conditions of compressors, pumps and even act as a flow switch. It is an integrated ultrasonic sensor, signal conditioner and RF transceiver with self-contained power operating in the 902 MHz to 928 MHz ISM license-free band. The field unit also has a built-in temperature sensor providing ambient temperature readings.

	Base Radio The Base Radio comes in either a weather-proof or explosion-proof housing. The output options include digital RS-485, Serial Modbus over RS-485, multiple 4-20 mA and contact switch closure. Integrate with existing control systems or use the Wireless Instrumentation Manager. The Base Radio is at the heart of the wireless solution. It communicates with all of the deployed field units and interfaces with your existing control system and/or the Accutech Wireless Instrumentation Manager for management. Various outputs include RS-485/RS-232 digital communications, multiplexed 4-20mA analog, discrete 4-20mA analog, Modbus, and Ethernet. One Base Radio can communicate with up to 50 field units. Multiple Base Radios can be used to accommodate larger installations. The Base Radio comes in NEMA 7 explosion-proof and NEMA 4X weather-proof and corrosion proof housing.

	Analog & Switch Output Modules The Analog, Digital and Analog/Digital Output Modules are Base Radio accessories providing four 4-20 mA outputs and/or eight switch closure outputs. Several modules can be daisy-chained to provide up to 100 4-20 mA outputs and/or 200 switch closure outputs.

	Wireless Instrumentation Manager The Wireless Instrumentation Manager is software providing real-time monitoring and configuration management. The Wireless Instrumentation Manager is the services management software for the Wireless Instrumentation product family. Services management encompasses both network management and applications (process monitoring) management in real-time. The software utilizes the client/server architecture model. The software can be installed on a server on your corporate LAN to run 7 by 24 and loaded onto one or many PCs to provide you with a services management console. Of course, the entire software can always be installed on a single PC.

	Wireless Instrumentation Hi-Gain Antennas High Gain antennas available for the Base Radio and most Field Units extend the transmission range for hard-to-reach areas.

Applications

	Acoustic Monitoring The characteristics of the Accutech Wireless Instrumentation system –- ready to go, complete, and absolutely non-intrusive –- allow its application to be extremely versatile. The same acoustic principles can be used for the measurement of process variables in a very wide range of industrial applications, including harsh and hazardous environments. The Acoustic Monitor Field Unit is ideal for monitoring pressure relief valves, steam traps, automatic tank cleaning (CIP) systems and other applications that generate ultrasound. It can also monitor on/off conditions of compressors, pumps and even act as a flow switch. It is an integrated ultrasonic sensor, signal conditioner and RF transceiver with selfcontained power operating in the 902 MHz to 928 MHz ISM license-free band. The field unit also has a built-in temperature sensor providing ambient temperature readings. How It Works The flow of gas or steam through orifices and piping generates ultrasound in the 40 kHz band. The acoustic signature (plot of amplitude over time) varies depending on the application and the process condition. The following are some examples of employing ultrasound to measure normal and failure conditions.

	Steam Trap Monitoring Manual inspections are an expensive way to catch the problem of stuck or plugged traps. To reduce your inspection costs, just bolt on the Wireless Instrumentation field unit and immediately catch leaks or other failed conditions. Focus your maintenance effort where it is needed, and save energy. It is estimated that between 10 and 20% of energy can be lost through malfunctioning steam traps. Problems range from “cold” traps that will not open and create poor quality, hazardous wet steam, to “blowing” traps that waste energy and also cause a hazard. Conventional, manual inspection of steam traps is a labor-intensive, costly, and error-prone task; nevertheless, it’s been the accepted monitoring method, until wireless technology from Accutech developed an efficient alternative.

	Cleaning-In-Place Monitoring Cleaning-In-Place (CIP) applications are an ideal fit for the Accutech Wireless Instrumentation monitoring system. The reliability, cost-effectiveness and versatility offered by this package allows its use to become a real competitive advantage for processors of pharmaceuticals, food, and beverage. In the food, beverage, and pharmaceutical fields, CIP challenges are many, and the way they are handled can drastically affect the quality of your end product. Often you don't find out that CIP didn't get performed according to specifications until an entire batch has been ruined - or worse, until the end customer finds out the product is spoiled. Conventional, wire-based monitoring of CIP, however, is expensive and awkward to implement. It can add so much to the final cost that product enhancement or new product development often have to take a back seat, a decision that carries obvious competitive disadvantages.

	Relief Valve Monitoring Process gas is expensive, and may pose an environmental concern. Identify leaks cost-effectively and without process interruptions by bolting the Wireless Instrumentation field unit to the valve. The monitor listens for leaks and immediately alerts you, so repairs can be scheduled. In the petrochemical and refining fields, process gas is expensive, and often dangerous to the environment. Continuous monitoring is the only way to identify leaks as soon as they occur, so maintenance can be performed right away. The expense of running conventional, wire-based 24/7 monitoring, plus the difficulties involved in reaching hazardous locations, pose a challenge that has been hard to solve until now.
