WIKA WIKA intelliGAUGE PGT23
WIKA Bourdon tube pressure gauges in stainless steel, with local indication and a 4…20 mA signal, in 100 and 160 mm diameters.
intelliGAUGE PGT23 is a mechanical Bourdon tube pressure gauge with an integrated electronic transmitter: pressure is read locally on the dial, without external power, while an electrical signal proportional to pressure is sent to the control room. The pointer position is read by a contactless angle sensor, so there is no wear or friction, and the mechanical indication stays readable even if the power supply is interrupted. The case has safety level S3 to EN 837-1, with a solid baffle wall and a back that blows out on overpressure; the series starts from the WIKA 23x.30 stainless steel safety pressure gauge.
The code shows the nominal size: PGT23.100 has a nominal size of 100 mm, PGT23.160 of 160 mm, while the 63 mm version, PGT23.063, has a separate data sheet (PV 12.03). PGT26 is the version with Monel 400 wetted parts. For a quotation we need the measuring range, the process connection, the type of output signal and whether the instrument will be installed in a hazardous (explosive) area. When the item is available locally or at the supplier, delivery takes 24–72 h, and for made-to-order items usually 1–4 weeks.

Frequently asked questions
Does the PGT23 pressure gauge still indicate pressure if the power supply is interrupted?
Yes. The indication on the dial is mechanical and needs no power supply; in a power interruption only the electrical signal sent to the control room is lost.
Can the PGT23 be installed in a hazardous (explosive) area?
Yes, in the 4…20 mA version for hazardous areas with the optional ATEX approval: II 2G Ex ia IIC T6/T5/T4 Gb for gases and II 2D Ex ia IIIB T135°C Db for dust. The Ex version must be requested explicitly when ordering.
What data should we send you for a replacement PGT23?
The code on the dial or the order number, the measuring range, the process connection and the output signal. The QR code on the dial leads to the serial number and the order number of the instrument, so a photo of the dial helps us.
Other WIKA series
We do not carry out installation or calibration on site (WIKA recommends an interval of one year, depending on operating conditions); we quote the pressure gauge by code and by the data in the data sheet.
