Product catalog summary

Overview: The 18.605 G is a submersible OEM pressure transmitter designed for level measurement in water and fuel oil tanks. It features a piezoresistive stainless steel sensor with an accuracy of 0.5% FSO according to IEC 60770.

Specifications:

Nominal pressure ranges from 0 to 10 mH2O.
Input pressure range: 0.1 to 1 bar with corresponding level measurements from 1 to 10 mH2O.
Overpressure capacity of 1 to 3 bar and burst pressure of at least 1.5 to 5 bar.
Output signal options include 2-wire (4-20 mA) and 3-wire (0-10 V or ratiometric).

Performance:

Accuracy: ≤ ± 0.5% FSO for PN > 160 mbar and ≤ ± 1% FSO for PN ≤ 160 mbar.
Response time: ≤ 10 msec for 2-wire and ≤ 3 msec for 3-wire systems.
Long-term stability: ≤ ± 0.2% FSO per year.
Thermal error: ≤ ± 0.3% FSO per 10 K within a compensated range of 0 to 70 °C.

Environmental and Electrical Protection:

Operating temperature range: -10 to 70 °C for medium, electronics, environment, and storage.
Ingress protection: IP 68.
Electromagnetic compatibility: Compliant with EN 61326.

Mechanical Stability:

Vibration resistance: 10 g, 25 Hz to 2 kHz according to DIN EN 60068-2-6.
Shock resistance: 100 g / 1 msec according to DIN EN 60068-2-27.

Materials:
