0 to 248.8 kPa (0 to 1000" H
2
O). 
Reference Accuracy:  
±0.10% of span for turndowns from 1:1 to 10:1 of 
URL (DVS205E). 
±0.075% of span for turndowns from 1:1 to 10:1 of 
URL (DVS205P). 
For spans less than 10:1 turndown:  
Accuracy = 
±[0.025 + 0.005(URL/Span)]% of 
span.  
Stability: 
±0.125% of URL for five years for ±50°F 
(28°C) ambient temperature changes, and up to 
1000 psi (68,9 bar) line pressure. 
Ambient Temperature Effect per 50°F (28°C): 
±(0.025% URL + 0.125% of span) spans from 1:1 
to 30:1. 
±(0.035% URL + 0.175% of span) spans from 
30:1 to 100:1. 
Static Pressure Effects:  
Zero error = 
±0.05% of URL per 1000 psi (68,9 
bar). 
Span error = 
±0.20% of DP Reading per 1000 psi 
(68,9 bar). 
Over-Pressure Limit: 3,626 psi (250 bar) applied 
on either or both sides without damage to the 
sensor. 
Burst Pressure Limit: 10,065 psi (694 bar). 
STATIC PRESSURE INPUT 
Range: Either Absolute or Gauge (100:1 
rangeability allowed): 
0 to 5516 kPa (0 to 800 psia/psig).  
0 to 25,000 kPa (0 to 3626 psia/psig). 
Reference Accuracy:  
±0.10% of span for turndowns from 1:1 to 10:1 of 
URL (DVS205E). 
±0.075% of span for turndowns from 1:1 to 10:1 of 
URL (DVS205P). 
For spans less than 10:1 turndown:  
Accuracy = 
±[0.03 + 0.0075(URL/Span)]% of 
span.  
STATIC PRESSURE INPUT (continued) 
Stability: 
±0.125% of URL for five years for ±50°F 
(28°C) ambient temperature changes. 
Ambient Temperature Effect per 50°F (28°C): 
±(0.05% URL + 0.125% of span) spans from 1:1 
to 30:1. 
±(0.06% URL + 0.175% of span) spans from 30:1 
to 100:1. 
Over-Pressure Limit: Same as URL. 
POWER 
Input at 0 to 75°C (32 to 167°F): 8 to 30 V dc, 10 
mW average.  
Input at –40 to 0°C (–40 to 32°F): 8.5 to 30 V dc, 
10 mW average.  
OUTPUT  
Serial Peripheral Interface (SPI).  
WEIGHT  
3.0 kg (6.7 lb).  
ENVIRONMENTAL 
Same as the FloBoss unit in which it is installed. 
Process Seals per ANSI/ISA 12.27.01  
Meets requirements for a Single Seal device as 
defined by ANSI/ISA 12.27.01. Installation must 
adhere to the following process temperature limits. 
Process Temperature (at transmitter isolator flange)
Standard Silicone Fill Sensor: -40 to 100°C (-40 to 
212°F). 
Inert Fill Sensor: -18 to 85°C (0 to 185°F). 
Note:  Process temperatures above 85°C (185°F) 
require you to lower the product’s maximum ambient 
temperature rating by a 1.5:1 ratio. To determine the 
adjusted maximum temperature rating, perform the 
following calculation: 
Adjusted max T
amb
 = Product Max T
amb 
- [(Actual 
Process T
amb 
- 85°C (185°F)) * 1.5]. 
Example:  
Adjusted Max T
amb
 = 75°C – [(95°C – 85°C) * 1.5] 
= 60°C. 
DIMENSIONS  
147 mm H by 163 mm W by 84 mm D (5.8 in. H by 
6.4 in. W by 3.3 in. D).  
VIBRATION EFFECT 
Sensor outputs will not shift more than +0.1% of 
URL per g from 5 to 2000 Hz in any axis when 
tested per IEC 770, Section 6.2.14. 
1. Consult factory for special ranges and materials which may be available. For example: 0 to 6.22 kPa (0 to 25" H

O) at 
±0.10% reference accuracy.
