Valve position indicator VPI for hydraulic system
-------------------
Manufacturer: Fluidwell(USA)
Model: F195 Series
The F195 has been developed for the valve position indication and monitoring in hydraulic systems. By using a bi-directional flowmeter to measure the volume displaced by the actuator, an accurate position of the system is calculated.The usual difficulties encountered in such applications include: very low flows, vibration, thermal expansion of the oil and high ambient temperatures. These are all well catered for in the design and operation of the F195. A wide range of options further enhances the capabilities of this model, including Intrinsic Safety for hazardous area applications and full Modbus communication.
Features
• Valve position calculated through bi-directional flow measurement.
• Displays the position as 0 - 100%, the moved volume and "open / closed" texts.
• Modbus communication link for remote monitoring.
• Re-calibration feature.
• Service counter displays the number of full strokes.
• Quadrature input to detect direction of flow.
• Auto backup of settings and running totals.
• Operational temperature -40°C up to +80°C (-40°F up to 176°F).
• Very compact design for panel mount, wall mount or field mount applications.
• Rugged aluminum field mount enclosure IP67 / NEMA4X.
• Intrinsically Safe - ATEX and IECEx approval for gas and dust applications.
• Explosion/flame proof II 2 GD EEx d IIB T5.
• Full Modbus communication RS232/485/TTL.
• Output loop or battery powered, 8 - 24V AC/DC or 115 - 230V AC power supply.
• Sensor supply 3.2 / 8.2 / 12 / 24V DC
