About the APR3110 Pressure Transmitter
The APR3110 pressure transmitter is designed to meet the requirements of the majority of hazardous applications where accurate low pressure measurement is required. Robustly constructed from stainless steel this range of pressure transmitters incorporates the latest silicon strain gauge technology together with a custom IC amplifier offering excellent stability and accuracy over a long service life. Electrical connection is via a detachable DIN connector allowing easy access to zero and span adjustment. Standard pressure connection is 1/2” BSP, but other options are available. Pressure ranges are available from 0- 100 mbar to 0- 900 mbar. Suitable for use with low pressure fluid and gas applications.
The APR3110 is intended for installation and operation in zone 0, gas group IIC, temperature class T4 and zone 20 dust and M1 mining. ATEX and IECEx approval and protection is by intrinsic safety when used with a safety or isolation barrier. DNV GL rules for classification of ships, high speed & light craft and DNV GL offshore standards.
