PT-503 Series
The PT- 503 has been engineered with advanced materials for most chemical applications.
The Series PT-503 Submersible Level Sensor brings precision level measurement to harsh chemical environments. Engineered with advanced materials, the PT-503 can be used in many places that stainless steel and PVC can’t go. With user-friendly analog output options and the ability to submerge it up to 21 meters (69 feet) underwater (30 psig), the PT-503 simplifies the process of obtaining dependable level measurements in challenging chemical environments.
• Simple to install
• High precision, aplified outputs 4-20 mA, 0.5 - 4.5 VDC (Ratiometric)
• Withstands most caustic or corrosive chemicals
