Description
Prinsip Kerja
Sensor mengaktifkan RTD platinum pada interval yang bisa dikonfigurasi (Heartbeat). RTD menghasilkan tegangan yang sebanding dengan suhu → dikonversi ke sinyal digital → data dikirim ke iMonnit Software melalui jaringan Wi-Fi.
Sensor dapat dikalibrasi untuk akurasi lebih tinggi, dan tersedia sertifikasi ISO-17025 (NIST) selama 13 bulan.
