Multi-variable sensors combine multiple sensing systems, such as pressure, temperature, and LVDT linear position sensors, in one package to reduce component count and power consumption. Explosionproof AST46PT provides pressure and temperature outputs from one process point. Along with microprocessor-controlled design, features include one-piece body, respective pressure and temperature measurement accuracy of ±0.1% and 1.0% BFSL, as well as -40 to +250°F and 20,000 psi max ranges.
