Barksdale catalogue of mechanical pressure switches: metal diaphragm, Bourdon tube, compact and diaphragm seal piston types with adjustment ranges.
This Barksdale catalogue presents the company's mechanical pressure switches, which connect or disconnect electric circuits and are used chiefly in hydraulic systems for monitoring minimum pressures, such as protecting pumps from dry operation, or maximum pressures as a warning device before a pressure relief valve reaches its limit pressure. The introduction discusses life span and accuracy, silver versus gold-plated micro switch contacts, contact protection for capacitive, lamp and inductive loads, and remedies for pulsation and vibration in the system.
The catalogue then covers metal diaphragm switches (D1S/D2S, D1T/D2T, D1X/D2X) and metal diaphragm differential pressure switches (DPD1T/DPD2T), Bourdon tube switches (B1S/B2S, B1T/B2T, B1X/B2X), diaphragm seal piston switches (E1S, E1H, P1H, P1X, MSPS), compact pressure switches (9671X/9681X, 9692X, Series 8000, Series 9000, KLK/KLM) and compact piston pressure switches (KD1). For each family it lists applications, adjustment ranges and a summary of main components, and the KD1 section adds dimensions, a hysteresis diagram, electrical ratings, electrical connection and options and accessories.

The metal diaphragm pressure switches cover adjustment ranges from -1 to 10.3 bar.
Set points are adjusted through a 5 mm hexagon socket.
No. The KD1 and KL series are only available with factory setting, so unauthorized adjustment is excluded.
A silicone cable, 3 x 0.5 mm2 and 600 mm long, is listed as option K2.
