Smart Wireless extends PlantWeb’s predictive intelligence into areas that were previously out of physical or economic reach, opening the door for new possibilities in process management.
WirelessHART™ Diagnostics: - Cycle counter - Configuration - Alerts - Power Status Modbus or OPC access to device variable information Control System Smart Wireless Gateway Engineered resin housing WirelessHART™ self-organizing network How many devices can be on a single Wireless Gateway? Up to 100. How many hosts can communicate with a Wireless Gateway? Many at the same time. For example: Legacy host systems (PLCs, DCS) and AMS® Device Manager.
Valvetop APPLICATIONs ™ Valve Control Solutions for Every Application 4-20mA Transmitters with HART Protocol The 2-wire position transmitter with HART will generate a nominal 4-20mA signal proportional to valve position output for full-range actuation of the valve. The transmitter is capable of generating signals below 4mA and above 20mA if the position sensor indicates an out-of-range value.
Linear Valve Monitors & Sensors Valvetop discrete valve controllers are the products of choice for linear valves of all types. Their precision sensing and proven reliability deliver the best position feedback available. Options such as 4-20mA transmitters with end-of-stroke sensors and HART protocol provide continuous monitoring and confirmation of valve position. Custom mounting kits are available to ensure reliable operation for the life of the valve package.
Valvetop APPLICATIONs ™ Valve Control Solutions for Every Application Dual Pilot Valve for Dribble Feed Control By using a unique dual valve option, the solenoids can be configured to allow two stage closing of the valve for applications such as tank filling where the valve needs to be throttled to prevent overflowing.
