Applications include:
Commercial Appliances and Food Processing – Precise liquid level and temperature control is critical to the performance of all food and beverage handling appliances. Food grade float switches are used to control pump-up and/or pump-down operations where liquid level accuracy is crucial. High or low level alarms, liquid measurement, and overflow protection are other common requirements that Madison float switches and temperature and liquid level sensors are adept at handling.

|
Specialty Vehicles – Madison’s continuous level sensors range from several feet in length all the way down to a few inches. These sensors give precise indication of liquid levels across the entire range of the tank from empty to full. If point level indication is critical, sensors can be designed with one or more level points on one sensor allowing for indications such as low level, high level or overflow alarms.
