DESCRIPTION
Senva’s PW31 Series is designed to streamline installation and provide maximum accuracy. Options for standalone transducer or 3-valve and 5-valve bypass assemblies allow flexibility and save time on installation and commissioning. The single-diaphragm element is temperature compensated to provides superior ±0.25% accuracy. The PW31’s compact, light, and rugged structure combined with IP65 stainless steel construction make it ideal for most installations and capable of withstanding the most rugged environments. Now available with a highly visible, loop-powered LED display. Just plug it in for ease of commissioning and troubleshooting (4-20mA version only).
APPLICATIONS
- Meet rigid accuracy and/or bypass specifications Demand measurement in HVAC systems for pump speed control and local indication
- Process control systems
- Measurement of gases, vapors, and liquids
- Measure pressure changes on pumps for efficiency regulation and energy savings
- Level measurement in tanks and vessels
- Filter status monitoring
- System leak detection
- Great for data center wet pressure sensing
FEATURES
- Temperature-compensated element for high accuracy in any environment
- 3-valve or 5-valve bypass options available to meet specifications
- DIN 43650 connector with screw terminals – no splicing necessary
- Versatile 1/2” FNPT allows simplified conduit connections – connect to any EMT, flex, or liquid-tight conduit
- Easy-access bleed valves for quick commissioning
- Calibration certificate included with every sensing element
- Optional LED display is highly visible and makes commissioning and troubleshooting simple (IP65)
ORDERING
Ordering the Correct Transducer
Using a lower range PSID transducer for higher PSIG applications will result
in inaccurate readings and may reduce the life span of the transducer.
See “line pressure effect” in specification section.
DIMENSIONS
Warning: The datasheet is designed for reference only. Refer to installation instructions that accompany the product and heed all safety instructions. Product improvement is a continuing process at Senva. Changes may occur to products without prior notice.
SPECIFICATIONS
- This is the maximum gauge pressure to maintain 0.25% accuracy.
- FS is defined as the full scale of the selected range. Accuracy includes non-linearity, hysteresis, repeatability, zero, and span tolerance.
- Stated operating range is for electronics only; Media temperature may be considerably higher. Use of devices outside of compensated range may result in drift.
Product improvement is a continual process at Senva and product features and specification may change without prior notice. Refer to instructions that accompany the product for installation and wiring.
