The Model 359 (or with HART, the 959) offers dynamic response to extreme temperature shifts, such as those caused during CIP/SIP processes. Using hydrostatic pressure to determine liquid level, the Model X59 ensures accurate and reliable measurement in ranges from 33 inches to 750 inches of water. The Model X59 is constructed of 316 stainless steel, providing maximum protection against corrosion. A flush diaphragm and 3A approvals, makes it ideal for the pharmaceutical industry. A unique, magnetically coupled external control system guarantees air and watertight in-use adjustments, with the ability for fine-tuning capability not available in other transmitters. The Model 359 and 959 comes in three different lengths for varying tank wall thickness.
