德国AB 8.8110 SF4 DIN 43 772
整体钻孔式 内螺纹温度计保护套管
Model SF4 Thermowell DIN 43 772 Form 4
Solid drilled for stem with male thread
Application
Thermowells are being applied to protect thermometer stems against process-related chemical and / or mechanical loads. Furthermore a thermowell, which remains at the measuring point, enables the unproblematic dismounting of the thermometer for
maintenance or repair.
Standard Versions
For thermometer stem with male thread, turnable or rigid,
our models A4, B4, A4.1 und B4.1
Construction Type
Solid drilled, that means completely manufactured of one piece, with cone, for high loads by the process (fl ows, pressures, temperatures and vibrations).
Process Connection
For welding
Details see reverse side
Connection to Thermometer Stem N
Female thread M18 x 1.5, G ½ or G ¾
Details see reverse side.
Internal Diameter d1
Ø 7 mm suitable for stem-Ø dF 6 mm
Ø 9 mm suitable for stem-Ø dF 8 mm
Ø 11 mm suitable for stem-Ø dF 10 mm
Ø 13 mm suitable for stem-Ø dF 12 mm
Available combinationsfor the connection to thermometer stem N and female diameter d1, see reverse side.
Total length L (normed length)
110, 140, 170, 200, 260, 410 mm
Details and installation length U see reverse side.
Material
1.4571 (316 stainless steel) or 1.7335 (13 CrMo 4-5)
Process Temperature / Process Pressure
Maximum allowed process temperature: 500 °C
Maximum allowed process pressure: 150 bar
Concrete process conditions (medium, fl ow rate, pressure, temperature) and the thermowell version (dimensions, material) could cause a reduction of the above mentioned maximum allowed values, see load diagrams DIN 43 772.
We can make a thermowell calculation for your concrete fi eld of application (see special version and options) upon request.
