LD290 Gage Pressure Transmitter Series
The LD290 Insertion Gage Pressure Transmitter Series is a line of an economical alternative for a gauge pressure measuring.
transmitter. It is based on a field-proven sensor using the robust capacitive technology to measure pressure. Time has proved that this type of capacitive sensor provides reliability,with longtime stability and high performance.
LD290 Gage Pressure Transmitter Types:
-
Gage Pressure - LD290:
The model LD290 is a pure 4-20 mA transmitter. Even though it has only analog input, its microprocessor-based electronics allow for total interchangeability with SMAR capacitive sensors. It automatically corrects sensor characteristics changes caused by temperature fluctuations.
-
Gage Pressure - LD291, LD292 e LD293:
The models LD291, LD292 and LD293 offer digital communication based in HART®, FOUNDATIONTM fieldbus and PROFIBUS PA - protocols, simplifying calibration and providing remote diagnostics. Their microprocessor-based electronic circuit allows for total interchangeability with SMAR capacitive sensors.
Alternatives:
Gage Pressure - LD290M
The LD290M model is a pure 4-20 mA transmitter. Even though it has only analog input, its microprocessor-based electronics allow for total interchangeability with Smar capacitive sensors. It automatically corrects sensor characteristics changes caused by temperature fluctuations.
Gage Pressure - LD2901M, LD202M, and LD293M
The LD201M, LD292M, LD293M models offer digital communication based in HART®, FoundationTM fieldbus and PROFIBUS PA - protocols, simplifying calibration and providing remote diagnostics. Their microprocessor-based electronic circuit allows for total interchangeability with Smar capacitive sensors.
Sanitary Gage Pressure Transmitter - LD290S, LD291S, LD292S and LD293S
The LD290S, LD291S, LD292S and LD293S models are specially designed for food and other applications where sanitary connections are required. With threaded or “tri-clamp” connections, it allows for easy and quick maintenance and cleaning.
Tri-clamp and other connections are compliant to 3A-7403 standard for food grade applications.
For further information, see the Smar SR301 Series Catalog.
Flanged Gage Pressure Transmitter - LD290L, LD291L, LD292L and LD293L
The LD290L, LD291L, LD292L and LD293L models have a flange mounted unit for direct installation on vessels. Extended diaphragms are also available.
Gage Pressure Transmitter with Extended Probe - LD290I, LD291I, LD292I and LD293I
The LD290I, LD291I, LD292I and LD293I models allow measurement of liquid level in open tanks, closed non-pressurized tanks, canals, wells etc. The measurement principle is based on measuring the column of fluid with the immersion of the hard probe into the liquid.
