INTRODUCTION / TABLE OF CONTENTS Step One
The LD30 Series Industrial Pressure Transmitters converts a single positive pressure into a standard 4‐20 mA
output signal. The transmitter can be used to accurately measure compatible gases and liquids with full scale
accuracy of 0.25%. Designed for industrial environments with a NEMA 4X (IP66) housing, this transmitter
resists most effects of shock and vibration.
CAUTION: Do not exceed specified supply voltage ratings. Permanent damage not covered by warranty will
result. This device is not designed for 120 or 240 volt AC operation. Use only on 13 to 30 VDC.
