GENERL DESCRIPTION CDP-00 series submersible or tank level pressure transmitter has been developed for measuring and monitoring water or liquid level in industrial and communal hydrostatic applications. The bluilt-in piezoresistive silicon measuring element designed offers great accuracy, excellent long term stability and very low temperature drift. The compact transmitter design allows versatile applications and are suitable for measuring dynamic and static pressure. The level pressure transmitters are available for absolute or relative pressure with wire current output and can be used for wide ranges of application in process control, level measurement of open weirs or stilling wells, tanks farms and paper liquors. It is designed as a general industrial level pressure transmitter with wide variety of available options to meet specific application requirements and constructed of water proofed.

INSTLLTION Each transmitter is subjected to an extended test program where zero and full scale output are individually adjusted as to guarantee the interchangeability of the transmitters. dditional calibration will not be necessary due to the excellent sensor characteristics. Whenever installing submersible level pressure transmitter, the following conditions should be considered ; - Select a proper nose cap according to the application. - Support cable should be installed when the cable length over 50m. - The venting hole should be opened to the atmosphere when applying gauge pressure sensor.
