| HD2004T-BG | Relative Pressure (GAUGE) transmitters |

HD 2004T and HD 20V4T are microprocessor pressure transmitter, the first one having a current
output (4 - 20 mA) and the second one a voltage output (0 - 5V, 1 - 5V or 0 - 10V).
The sensitive element consists of a bridge of piezoresistive resistances laid on a ceramic diaphragm.
When changing the applied pressure, the bending of this diaphragm causes a linear and proportional change of the bridge resistances.
The stainless steel case (30 mm diam.) includes both the sensor and the electronics: unscrewing the base equipped with fasten connectors, you access the keys to adjust the upper and the full scale.
A LED helps the user during the calibration procedure.
A BSP threaded connection and a slot on the case for a 24 mm wrench are provided to connect the transmitter with the plant under pressure.
On the other side, a 3/4 pole (depending on models) male fasten connector, the relevant outlet and a PG7 cable gland pursuant to DIN 43650 are provided to grant the electrical links.
Notes
A) To avoid storing wrong data, HD 2004T... and HD 20V4T series transmitters are provided with a protection system that automatically quits the calibration procedure without editing stored data,
if more than 45 seconds elapse since the last key has been pressed,.
B)
HD 2004T... and HD 20V4T... series transmitters automatically acknowledge the applied pressure as upper range pressure, if it does not exceed 15% of the nominal pressure, and as full scale pressure if it exceeds
the 40% of the transmitter nominal pressure.
