Product overview
The HPT-4 provides local digital pressure indication with a flanged flush-diaphragm process connection. Threaded, clamp and high-temperature-style connection forms are separate configurations.
Flanged pressure-transmitter configuration
The DN50 flange configuration combines a 0–5000 kPa pressure range, 4–20 mA output and a 24 V supply.
- Local digital indication
- Pressure values are shown in the round instrument window.
- Adjustable parameters
- Parameters can be adjusted using the control buttons.
Alternative process connections
Cooling-section connection reference
A stack of thin metal rings sits between the blue instrument head and the lower hexagonal fitting and threaded connection.
Clamp-connection alternative
A smooth metal neck ends in a compact clamp flange. This is a separate connection form from the DN50 flange configuration.
Threaded-reference dimensions
The separate threaded reference drawing gives a 92 mm upper housing width, 120 mm height above the threaded section and 19 mm threaded length. It does not dimension the DN50 flange or the clamp and cooling-section configurations.
