4.1 General Description
The IMVS2000v2 is designed to provide the Partial Stroke Test and SOV Test (in some
particular configurations). SOV test grant the solenoid valve integrity verification without
any actuator or valve movement, i.e.: perform the valve/actuator test and/or movement
able to verify and compare (diagnostic capability) signature values with ongoing test, in
particular, the continuously position verification (via encoder) and pressure verification in
actuator cylinder (these two functions are always active).
The functions above described are performed without any risk of process interruption.
A valve position sensor and sensors for external pressure are embedded on the
IMVS2000v2 unit: the analog output signals of the above sensors are monitored and
processed by logic control cards mounted within the device: through the above signals a
full control and diagnostic of every kind of valve actuator is available.
Typical applications, but not limited to, are the installation on all type of actuators, driven
pneumatically or hydraulically, for ON-OFF/ESD applications.
Different versions are available for:
• single or double acting actuators,
• actuators pneumatically or hydraulically operated,
• rotary or linear actuators,
• direct installation on actuator.
4.1.1 Main Features
In the following section the main features of the IMVS2000v2 are listed. For additional
details see Section 5.
POSITION SENSOR
The IMVS2000v2 is provided with an internal contactless position sensor. The position
(open or close) is directly takes on the shaft connected to the actuator.
PRESSURE SENSORS
The IMVS2000v2 can manage up to three internal pressure sensors for reading the actuator
(two sensors) and the pipeline (process) pressure.
CONFIGURATION-MANAGING INTERFACES
The IMVS2000v2 is provided with a powerful local operator interface, made of one 128x64
graphical OLED display and 3 push-buttons that allow entering the configuration data and
visualizing the values of variables or the status of the device.
Moreover, an RS232 and a Bluetooth serial communication ports are provided for the
connection with the “Biffi-Assistant” software tool (see [1] for details), to carry out
parameter configuration, or variables visualization or to download the recorded event data
for further analysis of pipeline behavior.
