Dimensions: 1/2” NPT
Terminal interface specification: 1/2” NPT
Explosion protection rating: dIIBT4
Protection rating: IP66
Process connection type: Isolated diaphragm
Mounting method: Flat flange bracket, 2-inch pipe mounting, all stainless steel (316L); complete set of subsurface installation flanges and mounting accessories included
Output: 4–20 mA, isolated; load impedance greater than 500 ohms ； On-site display: Digital LCD ； This instrument is intelligent; it operates on 24VDC power, automatically saves system data in the event of a power outage, and has self-diagnosis capabilities. 2) Temperature transmitters, which are temperature measurement instruments, are used to measure, display, and transmit the temperature signals of fluids within transportation pipelines. Measurement is carried out using a platinum thermistor, and the display and transmission unit form an integrated two-wire transmitter. Measurement range: 0–150°C Accuracy: 0.15 Measurement principle: Pt100 thermistor thermometer Installation method: 2-inch stainless steel thermal sleeve for isolation and protection (316L); threaded connection for the measurement tube Depth of insertion of the measurement tube: 200 Explosion protection rating: ExdIIBT4 Protection rating: IP66 Output: 4–20 mADC, isolated; load impedance greater than 500 ohms ； On-site display: Digital LCD power supply: 24VDC; automatically saves system data in the event of a power outage, and features self-diagnosis capabilities. ··························································- ---------------------------------------------------------- The above are the technical requirements for pressure and temperature changes. Is there anything wrong with the description of the installation method?
If you need instruments, feel free to contact me.
All stainless steel (316L), 2-inch tubing. Slightly overkill
Today, someone from Honey asked whether this is a remote-flange type or one that is installed directly online. I asked in the QQ group, and someone said that flanges should be used when there is a need to prevent direct contact with the medium. However, the person from Honey said that direct contact with the medium is necessary in all cases. My description indicated that it is of the diaphragm-type, so it should be a remote-flange type. This has confused me again; Emerson and E+h, however, didn’t say anything else after seeing this description
Interface type 1/2NPT is the thread specification you mentioned, right?
The description is fine; for pressure transducers, flange-diaphragm type instruments are used for installation, while for temperature transducers, 2-inch stainless steel heat sleeves are employed for isolation and protection (that is, external protective sleeves installed inside the equipment), with threaded connections.
Can it be installed directly using flanges, without the need for brackets or 2\" pipes?
