1: Terminal
head →  24 • 316L, high or low head, optionally with display window
• Aluminum, high or low head, with or without display window
• Polypropylene, low head
• Polyamide, high head, without display window

Your benefits:
• Optimum terminal access thanks to low housing edge of bottom
section:
– Easier to use
– Lower installation and maintenance costs
• Optional display: local process display unit for added reliability
• IP69K protection: optimum protection even with high-pressure
cleaning
2: Wiring,
electrical
connection,
output signal
→  6 • Ceramic terminal block
• Flying leads
• Head transmitter (4 to 20 mA, HART
® , PROFIBUS ® PA,
FOUNDATION™ Fieldbus), single-channel or two-channel
• Attachable display (optional)
3: Connector or
cable gland
→  28 • PROFIBUS ® PA / FOUNDATION™ Fieldbus connector, 4-pin
• 8-pin connector
• Polyamide cable glands
4: Extension
neck →  28 Quick fastener iTHERM QuickNeck or NPT 1/2"

Your benefits:
• iTHERM QuickNeck: tool-free removal of the insert:
– Saves time/costs on frequently calibrated measuring points
– Wiring mistakes avoided
• IP69K protection: safety under extreme process conditions
