▲Petroleum/Petrochemical/Chemical

▲Viscous media measurement

▲Occasions with high hygiene and cleanliness requirements

◐During the operation of the instrument, the instrument can be configured in real time, such as modifying the range, monitoring variables, etc.

◐The pressure signal can be intelligently linearized to ensure accurate and reliable measurement data.

◐There are reverse protection circuits and current limiting circuits on the circuit board to avoid accidental damage to the circuit as much as possible.

◐The configured parameters are stored in EPROM and can remain unchanged.

◐High precision and high reliability.

◐Solid components, pluggable electronic circuit boards, robust against vibration.

◐Explosion-proof structure, all-weather use.

◐Span, zero point and damping are continuously adjustable on site.

◐The indicating mechanism is completely isolated from the measured medium, with good sealing performance, high reliability and safe use.

◐High-quality sensing has high sensitivity and fast response speed, accurately reflects subtle changes in flowing or static pages, and has high measurement accuracy.

◐The single-flange liquid level transmitter has a large measuring range and is not limited by the height of the storage tank.

Output signal:DC4-20mA+HART protocol

Output method:Linear output

                        Square root output (remotely adjustable via configuration software)

Measuring range:

Zero and Span: It can be adjusted with the Span and Zero buttons of the machine, or remotely with the HART handheld smart terminal.

Positive and negative zero migration: when the zero point is negative, the lower limit of the range must be greater than or equal to -URL; when the zero is positive, the upper limit of the range must be less than or equal to +URL. The inspection range must be greater than or equal to the lower range limit.

Damping time constant: The time constant is adjustable, in increments of 0.1 seconds, from the minimum to 32 seconds, if the damping time is 0, the default is 0.1.
