SI Technologies Is Moving to Tustin

Seattle-based SI Technologies Inc., which has annual sales of nearly $45 million, said Monday it is moving its corporate headquarters to Tustin.

The company, which makes industrial sensors, weighing and factory automation systems and related products, will share space with Revere Transducers Inc., which SI bought last year. Tustin-based Revere, which also makes sensors, is SI’s largest subsidiary.

About 20 workers are involved in the move, which has been occurring gradually over the past six months.
