Electronic Vis-U-Tec

The Electronic Vis-U-Tec senses pressure differentials as low as 10 psig (0.69 barg) downstream from the Rupture Disk (Bursting Disc). Vis-U-Tec's piston fully extends, breaking the sensor's conductive circuit. Used with the Burst Disk Monitor, Vis-U-Tec's electrical warning triggers an audible or visual alarm.

Benefits

• Instantly Warns of a Ruptured Disk
• Reduces Plant Down-Time
• Reduces Product Loss
• Minimizes Environmental Pollution
• Re-useable - Reset the Piston Position

Applications

• Relief Valve Isolation
• For Double Disk Assemblies, Mid-Flange Installation Between Disks
• For Disks Free-Venting to Atmosphere or Down-Stream Piping
• Storage and Process Vessel Pressure Detection

Features

• After replacing the ruptured disk, reset the Vis-U-Tec by pushing the piston fully back into the unit.
• 12 inch (30cm) two-conductor cable
• 316 SS construction for all wetted parts contacting process fluids
• Viton O-ring seals the piston.
• Operating temperatures range from - 40 °F (- 40 °C) to 400 °F (204 °C).
• Maximum current: 250 mA
• Maximum voltage: 24 Vdc
• Suitable for intrinsically safe applications when used with certified apparatus (i.e. Zener Barrier)
• Available with Aluminum Piston option that provides visual warning only.

Installation

The Vis-U-Tec sensor fits into the Safety Head or piping outlet using a _ inch NPT screw connection.

Availability

Use the Vis-U-Tec sensor in applications that vent into enclosed volumes or for free-venting applications.
