What type of pressure transducer or sensor can I use with the ALiEn2?

The ALiEn2 line of controllers are designed to be ultra low powered, which does restrict the type of pressure transducer that can be powered and read. Please see the sections below for more details.

Single Pressure Transducer

ETC Pressure Transducer
1000 psi Pressure Transducer
ET-00000-0001-1001

A single pressure transducer is used for reading casing, line, or tubing pressure. The following table lists the required specifications.

DescriptionSpecification
Excitation Voltage5V
Output Signal0.5V to 4.5V
Supported Ranges100 psi – 5000 psi
CertificationClass I Zone 0/Div 1
Pressure Transducer Specifications

Pressure transducers are an available accessory from ETC. Visit the ALiEn2 Product Page for more accessories and replacement parts.

Differential Pressure

A differential pressure transducer is used to measure the pressure differential across an orifice plate, which is required if you are using the built in flow calculation. The following table lists the required specifications.

DescriptionSpecification
Excitation Voltage5V
Output Signal0.8V to 3.2V
Supported Ranges100 psi – 5000 psi
CertificationClass I Zone 0/Div 1
Differential Pressure Transducer Specifications

This interface is supported by the 1151L and 3051CD models of differential pressure transducer from Rosemount as long as it is ordered with Output Code M.
