Unit names and functions
Unit Symbol Part Functions
UNIT-A V1 Needle valve Adjusts the flow rate of the measuring gas supplied from UNIT-B.
V2 Needle valve Adjusts the flow rate of the reference gas or calibration gas
supplied from UNIT-C.
CV Switching valve Selects a gas to be supplied to the OHC-800.
UNIT-B PR Pressure
reducing valve
Adjusts the measuring gas supplied from GAS IN to a constant
pressure.
PG Pressure gauge Indicates the pressure of the measuring gas after pressure
adjustment.
(Display scale: 0 - 0.2 MPa)
FL Flow meter with
needle valve
Adjusts and indicates the bypass flow rate of the gas discharged
from BYPASS OUT.
(Display scale: 0.5 - 5 L/min, 1 - 10 L/min, 2 - 20 L/min
* Varies by the specification.)
UNIT-C PR Pressure
reducing valve
Adjusts the reference gas supplied from REF IN to a constant
pressure.
PG Pressure gauge Indicates the pressure of the reference gas after pressure
adjustment.
(Display scale: 0 - 0.2 MPa)
V Needle valve Adjusts the flow rate of the reference gas to be supplied to the
OHC-800.
(Display scale: 0.5 - 5 L/min, 1 - 10 L/min, 2 - 20 L/min
* Varies by the specification.)
CV Switching valve Switches the gas to be supplied to UNIT-A between the reference
gas and calibration gas.
UNIT-D RV1 Relief valve When the sampling system malfunctions, lets out an excessive
pressure from RELIEF OUT to prevent breakage of the OHC-800.
RV2 Relief valve
* The UNIT-B specification without pressure reducing valve and bypass line is also available.
