LD300 Series

The LD300 Series is a complete line of smart transmitters for differential, absolute, gauge, high static differential pressure and flow measurement as well as models for level, remote seal and sanitary applications.

The large acceptance of the LD300 line is due to the use of a capacitive cell as pressure sensor, which keeps the digital signal from the pressure reading up to the transmitter output, increasing the device accuracy and stability

Three options of communications protocols for configuration, monitoring and diagnostic are available: HART®, FOUNDATION™ fieldbus and PROFIBUS PA

• ± 0.075% accuracy for standard models;
• ± 0.040% accuracy for L1 models (high performance);
• ± 0.2% of URL stability - Guarantee for 12 years;*

LD400 Wireless HART

The LD400 WirelessHART™ Series is a complete line of smart transmitters for differential, absolute, gauge, high static differential pressure and flow measurement as well as models for level, remote seal and sanitary applications.

LD400 WirelessHART™ offers the best solution for all field applications demanding data wireless transmission and highest performance.

• ± 0.045% accuracy;
• ± 0.2% of URL Stability - Guarantee for 12 years;
• 200:1 rangeability;

• WirelessHART™ Protocol.

LD290 Series

The LD290M models are an economical alternative for gauge pressure and level
transmitters. It is based on a field-proven capacitive sensor that provides reliable, safe operation
and high performance.

• ± 0.2% accuracy;

• MTBF (Mean Time Between Failures) of 239 years;

• 40:1 rangeability;

• Digital communication via HART®, FOUNDATION™ Fieldbus, and PROFIBUS-PA protocols;

LD1.0

The Smar LD1.0 is an Economic Capacitive Pressure Transmitter and was designed for liquid, gas
and steam gauge pressure measurement in several industrial applications such as, industrial
process measurement, pneumatic and hydraulic systems, pumps and compressors, machine
and machining tools.

• ± 0.2% accuracy;

• 50:1 Rangeability;

• 4-20 mA output signal according to NAMUR NE43;

SR301 Series - Remote Seals

The SR301 series is a complete Remote Seal line, which is coupled on the pressure transmitters to meet different applications such as very high or very low temperatures, areas of difficult access or with too much vibration.

• SR301T: Flanged remote seal for general applications. The flush connection is optional.
• SR301E: Flanged remote seal with extension for general applications and it is very used
when the tank wall is coated.
• SR301P: Pancake type remote seal especially used in applications with limited
installation area. It may be supplied optionally with flush connection.
