Abstract
A pressure controller/calibrator has multiple modules. Each module has a stage, an elongated rail fixed to chassis of the controller or the module, and resilient guides fixed to the other of the stage or the chassis. In one embodiment, the rail has a proximate end at an edge of the chassis and a distal end inside the chassis. The distal end of the rail wider is than its proximate end. Between the two ends, the rail has concave contours that cooperate with convex springs in the stage to hold the stage at a desired location in the chassis.
