One:SKA/WSD-LDYThe type opener uses high-molecular sensitive convulsions of polymers, rapid response, stable and reliable, measured in the range-80°C~20°CTdAccuracy, full scale2°CTdThe product has automatic calibration of zero points and automatically heated the cleaning of chemicals attached to the sensor's surface, and its long-term use is extremely stable. It took more than 20 years for the high molecule to have a hard-on.-40°CTdWe've done a lot of basic research, and we've finally got the technology for low-wet sensitivity.-70°CTdChange to-50°CTdUnder the circumstances, the basic capacity is derived from300pFChange to305pFMore than all high-molecular exposures on the market.

II: Output signal:
Simulation:4‑20mA Two-line system (industry most common, circuit power supply)
Number:RS485 Modbus‑RTU, can also output spot, temperature, parts of the modelPPMV Water concentration.
Thread interfaces are common:G1/2、NPT1/4, which is twisted directly in the pipe; the detector cord burn filter protects the sensor and blocks dust particles.

Key selection parameters
Show some measure
Cold dryer: general 0 ~ ‑20℃Td
Suction dryer:‑40 ~ ‑70℃Td
Overdry high purity gas:‑80 ~ ‑100℃Td
Make the actual work as visible as possible in the middle of the scale and not be used at the limit of the scale for a prolonged period.
Precision: general industry ±2℃Td;high precision ±1℃Td Within. Low spot60°C) varies.
Pressure resistance: confirm pipe working pressure, compressed air 0.7‑1.0MPa, pressurized by high pressure.
Media: The gas has oil fog, dust, solvent vapour; the oil-heated condition requires pre-filtration sampling.
Output mode: Two lines 4‑20mA Still?RS485; power supplyDC12‑24V。
Calibration cycle: general 1‑2 Laboratory calibration is required for the year and sensors are slowly drifting.

V. ELEMENTS FOR ENHANCEMENT AND USE
Installed downstream of the dryer, at the front end of the gas point, to avoid a dead corner of the bend, water accumulation position; probes vertically or downwardly.
Vibration transformers measure pressure spots; pressure conversion is required when frequent pressure points are required.
No liquid water should be hit directly on the sensor, otherwise it will be damaged; there is a condensation risk to select an anticondensation sensor.
Gas flow speeds should not be too high; high-pressure high flow suggested the use of sample reduction circuits.
Oil vapour contaminates aluminium oxide sensors and must be filtered with oil.
