Absolute pressure transmitters reference a sealed vacuum and stay stable with barometric drift; vacuum gauges are local reference instruments that swing with weather and altitude. Pick the AP transmitter for control loops, the vacuum gauge for spot-checks.
Industrial level switch list prices in 2026 span roughly US$0.34 to US$1,500 per piece, with a 500-piece MOQ floor near US$0.34 for commodity units and 1-piece MOQ specialty units reaching US$1,500; hygienic and IP64 variants cluster in the US$30–US$100 band per piece.
A level switch is a binary point detector using a magnetic float; a magnetostrictive level transmitter is a continuous 4-20 mA/HART device with sub-millimetre resolution. Choose the switch for alarms and pump control, the transmitter when interface level or inventory accuracy is required.
Industrial level switches in 2026 split into 7 sensing families across 32-36 suppliers per category; the dominant selection gate is media + process connection, not price or brand. Floats, optical, RF admittance, capacitance, conductive, vibrating fork and thermal variants each map to a narrow fluid
Absolute pressure transmitter selection hinges on three choices: sensing element (silicon, strain gauge, or membrane), output protocol (4-20 mA HART, Modbus, or analog), and hazardous-area certification matched to the zone and process fluid.
Endress+Hauser PMD75B lists as "Price after login / on request" while Made-in-China bulk listings run US$15–902 across digital differential pressure transmitters on 2026-06-20; total installed cost typically lands 1.5–2.5× the unit list once manifolds, calibration and commissioning are added.

Specs that actually decide a purchase are resolution, re
Differential pressure transmitters (DP) measure the difference between two pressure ports; absolute pressure transmitters (AP) reference a sealed vacuum and output pressure relative to it. Choosing the wrong type ruins flow, level and atmospheric references — this comparison covers 8 OEM specs, key
Level switch selection starts with the medium: float switches handle clean liquids, RF admittance and capacitance probes cope with coatings, vibrating forks cover liquids and slurries, optical and conductive types target narrow niches, while a 7-step criteria matrix locks the spec.

Radar and ultrasonic level meters both remain widely stocked by industrial suppliers, with 2026 catalogs listing 69 ultrasonic models and parallel 26 GHz / 80 GHz FMCW radar families. Selection now hinges on vapor, foam, dust, temperature and clean-in-place constraints rather than base accuracy.
Industrial mechanical pressure switches for HVAC/pump duty list at US$2.20-2.50 per piece FOB China at 2-piece MOQ, while piston-style industrial switches from US/EU makers such as ASHCROFT cluster in the US$80-400 band on DirectIndustry aggregators; total landed cost is driven by certification, wet
Pressure switches and pressure gauges serve fundamentally different jobs on the same fluid loop: the switch opens/closes an electrical contact at a setpoint, while a pressure gauge provides a continuous human- or system-readable indication of the actual pressure value.
Pressure switch selection in 2026 hinges on matching sensing element, contact topology and process certification to the media; across six Directindustry vertical catalogs dated April–May 2026, mechanical differential and SPDT outputs dominate, with IO-Link PNP/NPN only visible in hygienic and limite

Industrial pressure transmitter list prices on 2026-06-20 span roughly US$11.95 for entry diffused-silicon units to US$526.90 for smart HART/Modbus models, with ATEX/IECEx variants adding a measurable premium over general-purpose CE units.
A pressure transmitter outputs a continuous 4-20 mA or digital signal proportional to process pressure for closed-loop control, while a pressure switch trips a discrete electrical contact at a preset threshold for on/off machine protection.
Pick dissolved oxygen meters for ppb-to-ppm aqueous oxygen in boiler feedwater, aquaculture, or brewery at-line; pick moisture analyzers for trace water content in solids, gases, and non-aqueous liquids. The two instrument classes overlap in "water measurement" but differ fundamentally in medium, se
Industrial dissolved oxygen meters in 2026 split into three buying lanes: lab precision (0.2 mg/L accuracy, Bante S60 Bluetooth), portable field (IP54, USB/Bluetooth, $482-507 FOB), and process/semiconductor (HORIBA HD-960L for low-concentration HF). Sensor type (galvanic vs polarographic) and outpu
