The digital test pressure gauges
TLDMM-A01 and
TLDMM-A02 are microprocessor based digital pressure gauges, made of
particularly high long-term stable analogue section and a 16 bit A/D
converter which ensure 65,000 internal divisions. These features,
together with a high accuracy class, make them ideal as a laboratory
instrument: in fact the digital test pressure gauges
TLDMM-A01 and
TLDMM-A02 are proposed as a first line
samples for Calibration Laboratories. The digital test pressue gauges
TLDMM-A01 and
TLDMM-A02 have internal batteries with 1 year autonomy, also
guaranteed by the Auto-PowerOff function, which activated if no
measurements changes are detected in the previous 30 minutes.
The user can select different engineering units (bar, mbar, psi, MPa,
KPa), resolution and digital filter, suitable for measurements to be
performed. In order to increase the level of integration among
components, a combined (traditional and SMT) technology has been used,
that makes this digital test pressure gauges more resistant against
mechanical stresses and vibrations and guarantees maximum reliability
for the circuit. The display also shows an analogue indication bar for
pressure, that is still on, even in the programming menu.
As an option, the digital test pressure gauges
TLDMM-A01
and
TLDMM-A02 are available with a RS232 interface. A connection cable
and a simple Software to read out the RS232 interface can be supplied on
request. |

Notes:
- If used together with our calibration handpump
LPP 30, we recommend the
volume-reducer order-code VRS-G12.
- For a safe pressure connection at pressure
ranges >1000 bar (>14500 psi) we recomment our optional double
sealing cone order-code TLDMM-DK.
We offer complete pressure calibration systems "
LPP-Kit"
