Barksdale Product Categories and Process Solutions
Explore the primary lines of Barksdale electromechanical pressure switches, smart IO-Link transmitters, temperature controllers, level indicators, and high-pressure Shear-Seal valves with technical parameters and application data.
Barksdale B1S, B2S, D1T, D2T, E1S, E1H, and P1H electromechanical pressure switches provide dependable process monitoring, alarm signaling, and safety cut-off across heavy-duty hydraulic power units, industrial compressors, pumping stations, and high-pressure lube oil loops. The sensing architecture incorporates precision metallic diaphragms, Bourdon tubes, and hardened sealed pistons spanning setpoint adjustment ranges from high vacuum up to 500 bar with proof pressures reaching 690 bar. Outfitted with high-reliability SPDT and DPDT microswitches featuring gold-flashed and silver contacts for low-current PLC signaling, these units prevent contact oxidation and signal loss. Heavy-duty die-cast aluminum enclosures rated NEMA 4X / IP65 withstand severe mechanical vibration, thermal shocks, and corrosive outdoor industrial environments. An external adjustment dial with a calibrated scale facilitates fast and accurate setpoint tuning without opening the hermetic enclosure.
Ranges 0.005..500 bar, 316L diaphragms, proof pressure up to 690 bar, SPDT/DPDT contacts.
Electronic Pressure Switches & Transmitters BPS3000, UDS7, 8000 Series
Barksdale BPS3000, UDS7, CS, 8000, and 9000 series electronic pressure switches and transmitters provide precision gauge, absolute, and differential pressure tracking for demanding fluid power, machine tools, and gas processing systems. The flagship BPS3000 features a 14-segment 4-digit LED display with dual 320-degree housing and screen rotatability alongside native IO-Link V1.1 digital communication protocols. Piezoresistive and ceramic sensing elements engineered from 17-4PH and 316L stainless steel maintain exceptional calibration stability with total accuracy within ±0.5% of span. The transmitters output standardized 4–20 mA / 0–10 V analog signals combined with programmable PNP/NPN transistor switch points for seamless SCADA and automation integration. An integrated peak-value memory logs transient pressure spikes, providing critical diagnostic telemetry for predictive machine maintenance.

Barksdale temperature control instrumentation encompasses BTS3000 smart electronic switches and T1X, T2X, MT1H, and T9692X direct immersion and remote capillary thermostats for industrial heat exchangers, bearings, and hydraulic power packs. The digital BTS3000 spans process temperatures from -50 °C to +150 °C, offering 0.1 °C resolution for setpoints and reset hysteresis via local programming or IO-Link networks. Remote bulb T2X capillary switches with armored capillary lengths up to 7.6 meters integrate ambient temperature compensation mechanisms to maintain setpoint accuracy irrespective of seasonal ambient swings. Heavy-wall thermowells fabricated from 316Ti stainless steel and brass protect sensing probes from direct pipeline velocity erosion and aggressive chemical contact. Complete support for Class A PT100 RTD resistance elements ensures superior signal stability across long wiring distances.

Liquid Level Switches and Transmitters BLS3000, UNS1000, UNS2000, BNA
Barksdale liquid level instrumentation delivers continuous and discrete level monitoring for hydraulic reservoirs, coolant tanks, fuel storage, and chemical process vessels. The lineup comprises BLS3000 capacitive electronic switches with rotatable displays, UNS1000 and UNS2000 magnetic reed float switches, and BNA bypass magnetic level indicators. Float assemblies accommodate up to 6 custom switching levels along guide tubes up to 3000 mm in length. Wetted components engineered from 316Ti stainless steel, titanium, polypropylene (PP), and PVDF ensure broad chemical compatibility across mineral oils, aggressive acids, caustics, and industrial process effluents. An optional integrated RTD temperature probe embedded inside the guide stem allows concurrent monitoring of fluid level and thermal status through a single tank port.
Stem lengths up to 3000 mm, up to 6 switch points, 316Ti/PVDF/PP materials, BNA bypass gauges.
Flow Switches and Flow Sensors BFS3000, UFS-1, UFS-2 Series
Barksdale flow measurement devices safeguard pumping infrastructure against dry-run damage and protect machine cooling systems and process loops from catastrophic overheating. The portfolio features BFS3000 solid-state calorimetric flow sensors with no moving parts alongside UFS-1 and UFS-2 mechanical paddlewheel and piston flow switches. The electronic BFS3000 detects fluid velocities from 0.03 to 3.0 m/s in aqueous media and 0.05 to 5.0 m/s in hydraulic oils. UFS-1 mechanical paddle switches install into pipe sizes from DN15 to DN500 with calibrated stainless steel vanes, triggering immediate interlock shutdown if coolant flow falls below critical pre-set thresholds. Multi-color LED bargraphs provide instantaneous visual confirmation of flow status and relay actuation on the plant floor.
Flow velocities 0.03..5.0 m/s, line sizes DN15..DN500, solid-state BFS3000 sensors.
Directional Control Valves Shear-Seal® Series II, 140, 9000, 3700
Barksdale directional hydraulic and pneumatic valves featuring proprietary Shear-Seal® technology are engineered for extreme service across heavy stamping presses, oilfield blowout preventers, and steel mill roll balances. The patented sealing mechanism utilizes floating metallic seats and an optically flat rotor that lap themselves during every actuation cycle, achieving near-zero internal leakage across extended operating lives. Series II, 140, 9000, 3700, and 4140 valves operate reliably at extreme working pressures up to 690 bar (10,000 psi) and flow velocities up to 15 m/s, shearing through abrasive particulate contamination without seal surface scoring. Hydrodynamically balanced rotor architecture ensures smooth, low-effort manual handle operation even under full rated line pressure.
Pressures up to 690 bar (10,000 psi), Shear-Seal® zero-leak design, 2-, 3-, 4-way patterns.

Diaphragm Seals, Pulsation Snubbers, and Mounting Manifolds
Barksdale protective and mounting accessories ensure long-term instrument reliability when interfacing with high-temperature, viscous, crystallizing, or highly corrosive industrial process media. The offering comprises diaphragm seals constructed from 316L stainless steel, Hastelloy C-276, Monel, and tantalum alloys, adjustable porous pulsation snubbers, cooling siphon coils, and multi-valve gauge manifolds. The diaphragm seals completely isolate sensitive transducer diaphragms from harsh fluid contact, transferring hydrostatic line pressure dynamically via high-integrity silicone-fill capillary lines without measurement degradation or mechanical dampening lag. Compact block-and-bleed manifolds permit swift on-site calibration and routine sensor swap-outs without de-pressurizing main process headers.
