LD293
Profibus Pressure Transmitter
The LD293 is from the first generation of PROFIBUS-PA devices. It is an economical alternative gauge pressure transmitter. It is based on a field-proven capacitive sensor that provides reliable operation and high performance.
This lightweight design eliminates the need of mounting brackets and transmitter support in many applications. Its microprocessor-based electronics allow for total interchangeability with SMAR capacitive sensors, correcting automatically sensor characteristic changes caused by temperature fluctuation.
The digital technology used in the LD293 enables the choice of several types of transfer functions, an easy interface between the field, the control room and several interesting features that considerably reduce the installation, operation and maintenance costs.
