Variable Speed Control: Maintains precise airflow to optimize latent and sensible heat removal

It features a versatile operating temperature range of 140°F to 240°F and a factory-set fixed high limit at 240°F to prevent thermal runaway

MAMAC Systems PR-275-R3-VDC Pressure Sensor 321042-401 the 10J42 is calibrated specificallyFor high precision air pressure monitoring, the MAMAC Systems PR 275 R3 VDC is a versatile low pressure sensor engineered with glass on silicon (Gl Si) capacitance technology. This veteran grade differential pressure transducer provides superior stability by addressing common field issues like zero drift and calibration shift. It offers six field selectable pressure rangesincluding 0 5"wc, 0 2. 5"wc, 0 1. 25"wc, and compound ranges like 2. 5" to 2.
