A USB port simplifies setup on a Windows PC or Android mobile device with the company’s Agility app. Software menus help users set the sensor type, bridge configuration, excitation source, filtering level, and I/O ranges. Advanced capabilities let users fine tune scaling of I/O signals, adjust excitation levels, and calibrate the bridge. Universal output supports six ranges including 4-20 mA, 0-10 V and ±10 V. Flexible power accepts a 9-32 VDC supply at the terminals and a rail power bus option can supply multiple units from a single connection or establish redundant power. The narrow 17.5 mm housing mounts easily on a DIN rail. Hazardous location approvals, high noise immunity, and a -40 to 70 °C operating range make these transmitters suitable for use in harsh environments. The unit’s input circuit allows true six-wire bridge measurement and includes an adjustable bridge excitation supply (four to 11 VDC) with a remote sense feature. Sense wires ensure the programmed excitation voltage is applied at the sensor and enable lead-wire compensation. The differential input performs true ratiometric conversions for extremely stable measurements that remain accurate over time and temperature. Lead break detection is inherent in the device. Three-way isolation between input, output and power increases safety and noise immunity.
