LTD Differential Transmitter
Brand: Winters Instruments
Features
- Designed to measure the wet to wet differential pressures of liquids and gases
- Compact, efficient design available in Low or High psi ranges that facilitates installation in tight spaces
- Low Range housing is constructed of stainless steel and aluminum
- High Range housing is made from a 316-grade stainless steel ideally suited for an industrial environment
- Fast response sensor and signal conditioned electronic circuitry provide quick and accurate readings
- Unique isolation system responds to pressure changes approximately 20 times faster than conventional transmitters with ranges below psi: 100 (kPa: 689.5, bar: 6.895) [Low Range model]
- CE approval is standard on all models
- NEMA 4 approval is standard on the Low Range model
