$500+ Orders on Lesman.com Ship Free via UPS Ground
Dual head or inline absolute pressure smart transmitter, mmHgA and PSIA ranges, accuracy ±0.065% span, integral and remote configuration available, FM, CSA, ATEX approvals, SIL 2/3 certified.
Honeywell SmartLine STA700 absolute pressure smart transmitters can help you reduce project costs, cut startup and commissioning time, lower total maintenance costs, reduce repair time, enhance safety, lower operating costs, reduce unplanned downtime, and improve product quality. They are ideal for vacuum applications that require robust performance, including low-pressure measurement in vacuum distillation columns, where energy savings are directly proportional to the vacuum in the column.
SmartLine ST700 transmitters are designed to replace older ST3000 Series 900 transmitter models. To replace or upgrade an ST3000 Series 100 model, see the Honeywell ST800.
