RKI M2A adalah pemancar canggih yang dapat beroperasi sebagai monitor independen yang berdiri sendiri atau sebagai bagian dari sistem terintegrasi. M2A terhubung dengan sinyal analog atau digital ke hampir semua pengontrol, PLC, atau DCS. Prosedur pengaturan disederhanakan dengan tombol tekan yang mudah digunakan dan menu OLED. Alat ini menggunakan teknik tongkat magnet untuk melakukan kalibrasi non-intrusif. M2A menyediakan fitur koreksi penyimpangan nol otomatis, yang menghasilkan pembacaan yang lebih stabil dan mengurangi kebutuhan penyesuaian karena penuaan sensor.
Housing M2A tidak perlu dibuka untuk zeroing atau kalibrasi, sehingga tidak perlu mendeklasifikasi area untuk pemeliharaan rutin. Hal ini dirancang agar kalibrasi lapangan yang lengkap dapat dilakukan oleh satu orang. Konstruksi sensor diberi peringkat Kelas I, Div. 1 Grup B, C, D untuk bahan mudah terbakar, CO, H2S, O2, dan CO2, dan Kelas I, Div. 2 untuk semua bahan beracun lainnya.
Pemancar menyediakan output 4-20 mA sebagai tambahan dari output digital Modbus. Pemancar ini juga memiliki dua tingkat alarm dengan relai, ditambah alarm gagal dengan relai. Tampilan digital konsentrasi gas, serta alarm dan lampu status, dapat dilihat melalui jendela depan.
Sensor racun adalah sensor plug-in tipe elektrokimia, yang memberikan kekhususan tinggi, respons cepat, dan masa pakai yang lama. Desain plug-in memungkinkan penggantian cepat di lapangan tanpa memerlukan alat. Sensor beracun dirancang untuk digunakan di lokasi berbahaya Kelas I, Div. 2. Sensor tersedia untuk NH3, AsH3, Cl2, ClO2, HCN, PH3, dan SO2
M2A mewakili teknologi terdepan terbaru dalam sensor / pemancar saat ini.
