- How does the GX Series Carbon monoxide sensor operate?
The GX series sensors use a digitally profiled metal oxide semiconductor (MOS) to measure CO levels,
and are available with current (4-20 mA) or voltage (0-5/01-0 VDC) outputs The non-adjustable N.O.(open on alarm)
relay is programmed to alarm at 35ppm. Some models are configured with an auxiliary alarm output;
indicated by two orange wires at the bottom of the device. The auxiliary output is configured to provide a contact closure
and audible (siren) alarm when the CO level reaches 100ppm for 30 minutes.
- What’s the difference between a PW sensor range vs. max pressure?
The PW series is rated with it’s maximum gauge/differential pressure. For example the maximum pressure range for PWXX04S is 100psi.
This model as with all PW models has four selectable differential pressure ranges. Please see chart for details.
The range selected will be the range represented by the output signal.
PWXX04S with range B selected (see chart). Output set to 0-10VDC
HI port: 100psi
LO port: 50psi
Both pressures are within the 100psi range and the differential is 50psi. Range B sets the output signal to 0-50psi
so the output signal will be 5VDC at 25 psi.
- What does Proof Pressure vs. Burst Pressure mean?
PW series wet pressure transducers are rated for 2x proof pressure and 5x burst pressure.
Proof pressure is the amount of overpressure the unit can be subjected to without damage.
The unit can be exposed to 2x the rated maximum gauge pressure and be expected to work properly once pressure returns
to within the rated pressure range.
Burst pressure is the amount of overpressure at which the unit will certainly be damaged.
Damage may occur at any point between proof pressure and burst pressure.
Note that the unit will not read accurately if pressure is above the rated maximum.
- What modbus registers can I read/write to?
Complete data on all modbus products is available at http://www.veris.com/modbus.
- Can I use the H8100 series meters on delta services?
No. The H8100 series meters require a connection to a neutral wire. Without such a connection the meter will not function.
A connection to a ground is not an acceptable substitute for a neutral connection.
- Does Veris have a RTD/Thermistor table?
Yes. RTD/Thermistor table (.pdf)

- How do I make changes to the factory default BCM Board names?
All H704/H726/H663/BCM products ship with the name of the unit set to BRD1. This can be changed with Mnode software or with a
modbus write to registers 274/275. Mnode is a free software program and is available for download on Veris’ website
in the Modbus support section.
