3051 Remote Transmission Differential Pressure TransmitterDetailed product description：

The 3051 remote differential pressure transmitter provides several reliable measurement methods to avoid direct contact between the side medium and the isolation diaphragm of the transmitter. The transmitter with remote transmission device is suitable for the following situations
1. It is necessary to isolate the high-temperature medium from the transmitter.
2. The tested medium has a corrosive effect on the sensitive components of the transmitter
3. Suspended liquids or high viscosity media
4. The tested medium solidifies or crystallizes due to changes in environment or process temperature
5. The replacement of the measured medium requires strict purification of the measuring head, which must be kept clean

Performance indicators of 3051 remote transmission differential pressure transmitter

Reference conditions: Under the conditions of no migration, capillary length of 1.53m filled with silicone oil, and 316 stainless steel diaphragm
Temperature effect: On one side of the remote transmission device (typical case), there is a remote transmission device with a capillary tube of 1.53m
Flat type: with an error of less than 0.62Kpa/55 ℃, the error increases by 0.20Kpa for every 1.53 meters increase in the use of silicone oil filled capillary tubes
Threaded and flanged: with an error of less than 1.99Kpa/55 ℃, using a silicone oil filled capillary increases the error by 0.62 Kpa for every 1.53 meters increase
Vibration effect: It can withstand vibrations up to 200Hz in any axial direction, causing an error of ± 0.05% URL
Power supply impact: less than 0.005%/V of the adjusted range
Load impact: No load impact
Installation location impact: Approximately 250Pa zero point migration, can be eliminated through calibration, with no range effect.
RF interference impact: Under the conditions of frequency 30-1000MHz and maximum field strength of 10V/m, it causes drift of ± 0.1% of the adjusted range
