HYDROSENSE HS2410 

Revision 5.0 

P a g e   5  |  27 

 

SPECIFICATIONS 

Specifications are subject to change without notice: 
 

Specification 

Details 

Power Input: 
(Specify at the time of 
order) 

100 -130VAC* 

OR

 207 - 253VAC* 50/60 Hz, 200 VA max, 

OPTIONAL: 24 VDC @ 3.5 A max 

*Operational Range 

User Interface: 

 

Display 

Four line LCD with simultaneous display in PPM, Cal Location, current 
temperature, and bar graph 

Communication Interface: 

RS-485 Modbus, optional HART or Fieldbus Foundation module for uni-
directional communication of ppm. 

Relays / Analog Outputs: 

 

Relay Outputs 

4 independent SPDT, 10 amp (7 amp if used in Class I, Div 2 applications), 
dry contacts with LED panel indication 
2 setpoint alarm relays (R1 & R2): user settable alarm points and delay time 
(0-99 seconds delay on) 
1 maintenance alarm relay (R3) 
1 Lamp or controller failure alarm relay (R4) 

mA Signal Output 

4-20 mA DC, 900 Ohms, isolated, field scalable 

Instrument Performance: 

 

Measuring Range 

0 - 5000 ppm Hydrocarbon in Water 

Instrument Accuracy 

± 0.1 PPM 

Process Accuracy 

+/- 1.0 ppm typical 
The process accuracy is reflected by the site calibration to a known 
hydrocarbon concentration and a stable background water.  Changes in the 
hydrocarbon make-up and variations in the process may affect the 
instrument output. 

Sensitivity 

145 PPB (diesel reference) & 463 PPB (crude oil reference)  

Calibration 

A library of up to 10 calibrations with up to five concentration entry points per 
calibration to maximize accuracy 

Signal Filtering 

20-1000 samples/average 

Environmental:  

 

Ambient Temperature 

5-55 

C  

Protect from direct sun or rain. Instrument shelter or indoor use is 
recommended. Higher temperatures may be accommodated with air 
conditioning. 

Relative humidity 

Up to 90% (non-condensing) 

Process Requirement: 

 

Process Sample 
Temperature 

0-40 

C without cooler; above 40 

C with cooler. 

Inlet Flow Rate 

Minimum: 1.0 L/M (continuous and stable) 
Optimum: 3.0 to 5.0 L/M (continuous and stable) 

Inlet pressure 

Minimum 2 psi, maximum 1000 psi, 

*

minimum 20 psi when equipped with 

optional cooler.  

*For safety reasons a reducing valve should be used for pressure above 100 psi.
