Pressure

The STD98 features a thick film capacitive 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.

Optional Accessories:

  • TR202 Relay  Digital readout + 2X active relays/ 1X F.S. Relay + passive 4…20mA out
