Model TY783 adalah sensor suhu tipe celup (immersion temperature sensor). Keluaran resistansi Pt100-nya (setara dengan JIS* C1604 Kelas A), yang dikombinasikan dengan perangkat elektronik yang memiliki input Pt100, digunakan untuk pengendalian, penunjukan (indikasi), dan pencatatan suhu fluida proses di dalam pipa, tangki, atau penukar panas (heat exchanger).
Model TY783 juga digunakan sebagai sensor suhu untuk duct atau ruang (chamber).
