The STD81 features a piezoresistive ceramic sensor and a rotatable 5 digit LCD display that permits the user to visualize the variation of either the level or the pressure of the process by value, percentage or a real time graph. The STD series provides a 4…20mA analog signal with superimposed HART communications protocol, programmable Zero/Span adjustment, decimal point, damping and display mode parameters via three programmable buttons.
