Failure Alarm
In case of sensor or circuit failure, the self-diagnostics drives the output to 3.6 or 21.0 mA,
according to the user's choice.
Turn-on Time
Performs within specifications in less than 5.0 seconds after power is applied to the transmitter.
Volumetric Displacement
Less than 0.15 cm
3
(0.01 in
3
).
Overpressure and Static Pressure Limits
From 3.45 kPa abs. (0.5 psia)* to:
8 MPa (1150 psi) for range 1.
16 MPa (2300 psi) for ranges 2, 3 & 4.
32 MPa (4600 psi) for models H & A5.
40 MPa (5800 psi) for model M5.
52 MPa (7500 psi) for model M6.
* except the LD301A model.
Flange Test Pressure: 60 MPa (8570 psi).
For ANSI/DIN Level flanges (LD301L models):
CLASS
RANGE
TEMPERATURE
150 lb
6 psia to 275 psi (-0,6 to 19 bar)
38ºC
300 lb
6 psia to 720 psi (-0,6 to 50 bar)
38ºC
PN10/16
-60 kPa to 1,4 Mpa
120ºC
PN25/40
-60 kPa to 4 MPa
120ºC
These overpressures will not damage the transmitter, but a new calibration may be necessary.
Humidity Limits
0 to 100% RH.
Damping Adjustment
Through the programmer: adjustable for any value greater than or equal to 0 seconds,
added to the sensor response time (0.2 seconds)
Configuration
Can be done through digital communication using the Hart Protocol or, partially, through local
adjustment.
