The transmitter features a circuit design with a microprocessor at its core and is enhanced with advanced digital isolation technology, ensuring high anti-interference and stability. Equipped with a built-in temperature sensor, the transmitter has functions of real-time temperature compensation to improve measurement accuracy and reduce temperature drift. It offers excellent long-term stability, high reliability, and robust diagnostic capabilities. Structurally, the transmitter can be easily calibrated, configured, and set up using a HART communicator.
- Developed with advanced monocrystalline silicon pressure and differential pressure sensor technology and packaging processes, this transmitter delivers industry-leading performance.
- One-way over-pressure protection up to 25MPa
- Designed with a microprocessor at its core, complemented by advanced digital isolation technology, the instrument exhibits exceptional anti-interference capability and stability.
- High-performance 24-bit ADC ensures high measurement accuracy.
- The latest one-click clearing function does not compromise the electrical protection level, providing a safer and more efficient user experience
Span limit:The upper and lower limits of the span can be set freely, provided that the calibrated span is greater than or equal to the set span. It is recommended to select the lowest possible span ratio to optimize performance.
Installation position: The change of installation position perpendicular to the membrane does not cause zero drift. If the position deviates more than 90° from the membrane plane, a zero offset within ±0.4 kPa may occur, which can be corrected through zero-point adjustment without affecting the span.
Output: Two-wire 4-20mA, compliant with NAMIR NE43 specification, with superimposed digital signal (Hart protocol); linear or square root output are selectable. Four-wire RS485 output available; ModBus communication protocol.
Output signal limit:
Low alarm mode Imin (min): 3.9 mA
High alarm mode Imax (max): 21 mA
Fault alarm: if a sensor or circuit fault occurs, the self-diagnosis function will automatically output 22.0 mA.
Response time: The damping constant of the amplifier component is 0.1s; the sensor time constant is 0.1 ~ 1.6 s, depending on the span and span ratio.The additional adjustable time constant is: 0 ~ 100s.
Warm-up time: < 15s
