    About Pressure Gauges
    industrial info icon

    Find a gauge with the right connection material and dial type—many with traceable calibration certificates.

    Low-Pressure Differential Gauges with Color Indicator

    A band of green, yellow, and red provides a clear indication of changes in differential pressure. Gauges are commonly used to indicate clogged filters.

    For Liquids

    For Liquids with Solids

    FM and C-FM approved, these transmitters safely measure liquid levels where explosive gas or dust may be present. Set them at the bottom of your tank in applications that make traditional mounting difficult. They sense liquid levels by measuring the pressure from the weight of the liquid above them. All continuously send measurements, so you can monitor status and manage components in your system. Also known as level loggers, level sensors, and pressure transducers.
    For Liquids with Solids—Transmitters for liquids with solids have an unobstructed sensing element that resists clogging and sludge buildup in water with particulate and sewage.
