Model 359 Sanitary Level Transmitter
Legacy Products
This model is no longer available with no replacement part
359 is designed for 3A sanitary clean in place applications. 359 comes standard with Hastelloy wetted parts, providing excellent corrosion resistance to caustic materials. 359 has sealed external adjustments and capable of being ranged down if lower range measurements are required.
