Stable performance factory directly 4-20ma strain gauge pressure transmitter

Directly connectable to 1½in and 2in flanges
The transmitter is connectable to 40A(1½B) and 50A(2B) pipes without a reducer.

Minimum environmental influence
The Advanced Cell design, which protects the pressure sensor against changes in temperature, static pressure, and overpressure substantially reduces total measurement error in actual field applications.

Application flexibility
Various options that render the CXT suitable for almost any process applications include:
– Built-in RFI filter and lightning arrester
– 5-digit LCD meter with engineering unit
– Stainless steel electronics housing
– Wide selection of anticorrosion materials

– High temperature, high vacuum seals

Performance Specifications for Linear Output
(Silicone oil fill, 316L SST isolating diaphragms.)

Accuracy rating (including linearity, hysteresis, and repeatability)
Standard:
For spans greater than 1/10 of URL: ±0.25% of span
Option (For 21st digit code H and K):
For spans greater than 1/10 of URL: ±0.1% of span
Stability
±0.2% of upper range limit (URL) for 10 years.
Temperature effect
Effect per 28℃ change between the limits of -15℃ and +65℃
Zero shift:
±0.5% of URL /28℃ (When span ≥ 1/6.5 URL)
/28℃ (When span < 1/6.5 URL)
Total effect:
±0.75% of URL /28℃ (When span ≥ 1/6.5 URL)
/28℃ (When span < 1/6.5 URL)
Note: Above specifications are based on the conditions that flange and sensor unit is at the same temperature and in the same level. If temperature is different at flange, capillary or sensor unit, output variation may increase.
Over range effect
Zero shift: ±0.2% of URL for any over range to maximum limit
