PBLTX-10-40 submersible, intrinsically safe (IS) level transmitter from Dwyer Instruments runs at 30 VDC, 10 psi and up to 93 °C in a 316 stainless-steel (SS) housing with a 40-ft, ETFE cable. It’s manufactured for years of trouble-free service in harsh applications. PBLTX-10-40 measures the height of liquids above their position in a tank referenced to atmospheric pressure. The transmitter consists of a piezoresistive sensing element, encased in its 316 SS housing with a cage and large-diameter, 316 SS, diaphragm seal. PBLTX is UL-approved IS for use in hazardous locations when used with a proper barrier.
