Self calibration The analog-to-digital measurement circuitry automatically self-calibrates for each temperature update by comparing the dynamic measurement to extremely stable and accurate internal reference elements. Vibration effect Tested to high pipeline vibration specifications per IEC with no effect on performance. Materials of construction Enclosure Housing - Low-copper aluminum Paint - Polyurethane Cover O-ring - Silicone Terminal Block and Power Module PBT Antenna PBT/Polycarbonate (PC) integrated omnidirectional antenna Mounting Transmitter can be panel mounted, or be mounted onto a -in. pipe stand (with option code B6).
