Hardware Specifications

4-20 mA HART Loop Protocol and Channel Isolation

The transmitter conditions raw electrochemical or catalytic bead sensor inputs into a standardized 4-20 mA analog current loop proportional to detected gas concentrations. Channel-to-channel isolation and galvanic barrier circuits protect internal processing units from ground potential shifts and high-voltage transients across industrial control loops. FOUNDATION Fieldbus and Profibus PA connectivity frameworks support integrated data exchange, while cold junction compensation (CJC) maintains thermal stability across process interfaces without introducing measurement error.

Frequently Asked Questions

Q: Does the unit incorporate onboard dry contact relays for local alarm activation?

A: No. This specific configuration operates strictly via a 4-20 mA current loop without internal relays, offloading alarm switching logic to upstream control systems.

Q: What is the nominal loop power supply voltage required for stable operation?

A: The transmitter requires a regulated 24 VDC power supply connected across the two-wire loop terminals.

Q: How is periodic sensor calibration performed on the Satellite XT unit?

A: Calibration is executed by applying a certified test gas mixture directly to the sensor head while adjusting zero and span potentiometer settings via the internal interface.

Field Installation Guidelines

1. Mount the transmitter enclosure vertically on a rigid structural surface or DIN rail in an area representative of potential gas accumulation zones.
2. Terminate the 4-20 mA signal loop using shielded twisted-pair cable, ensuring the drain wire is grounded exclusively at the control panel earth bar.
3. Protect the sensor inlet from direct water impingement and particulate accumulation by utilizing an appropriate weatherproof splash guard.
4. Verify loop output current and zero gas baseline levels using a calibrated multimeter prior to system commissioning.
