The probe body and the probe head are connected by a cable. Length options for this connecting cable depend on the probe model. The probes are compatible with Vaisala Indigo transmitters. They can also be connected to Vaisala Insight software for configuration, calibration, diagnostics, and temporary online monitoring.

Let the cable hang loosely to prevent condensed water from running along the cable to the probe body or probe head. Attach the probe body to a wall or other surface using the two mounting clips (Vaisala item 243257SP) supplied with the probe. Each clip attaches to the installation surface with one screw (screw hole Ø...
DMP5 is built for direct measurement in hot and dry processes, up to +180 °C (+356 °F). As the probe can be directly placed in the process, there is no need for a sampling system or trace heating.
Installing with Mounting Flange 210696 Mounting flange 210696 is designed for attaching Ø13.5 mm probe heads through the wall of a process chamber or duct. The flange kit includes a flange, a sealing ring, and screws. 75 [2.95] 50 [1.97] Drilling 16 ...

Vaisala DRYCAPâ Dew Point Probe DMP6 is designed for humidity measurement in industrial applications with very high temperatures. High temperature tolerance is achieved using a passive cooling set that conducts heat away from the probe and reduces temperature to optimal range for the sensor.

Make a round 89.5 + 0.5 mm (3.52 + 0.02 in) hole in the process wall. Install the cooling set horizontally whenever possible to ensure the best possible cooling performance.
8. Tighten the locking screws to lock the probe head in place. 9. If installation of cooling fins is required, attach them around the cooling bar using a 5-mm Allen key. Place the cooling fins so that the locking screws are not obstructed. Tighten the two mounting screws so that the fins have good thermal contact with the cooling bar.
41 [1.61] Figure 10 DMP7 Dimensions Vaisala DRYCAPâ Dew Point and Temperature Probe DMP7 is designed for low-humidity applications. Thanks to its short probe length, it fits in installations with limited space such as semiconductor manufacturing equipment. Other applications include industrial drying, compressed air systems, dry rooms, and blanket gases in metal heat treatment.

ISO1/2” or NPT1/2” Figure 12 DMP8 Dimensions Vaisala DRYCAPâ Dew Point and Temperature Probe DMP8 is designed for industrial low- humidity applications such as industrial drying, compressed air systems, and semiconductor industry. It can be installed in a 1/2" NPT or ISO thread with adjustable insertion depth.

Figure 13 DMP8 Probe Head Clasp nut, 24 mm hex nut Fitting body, 27 mm hex head Leak screw (on ISO 1/2" fitting body HM47432 only) Fitting body with a leak screw can be useful when the probe head cannot be installed directly in the pressurized process or process pipe.
Tightening the Clasp Nut 1. Adjust the probe to a suitable depth according to the type of installation. 2. Tighten the clasp nut to finger tightness. 3. Draw a line on the fitting screw and the clasp nut to mark their position. 4.

3. Tighten the ball valve assembly by turning from the ball valve body. CAUTION! Tightening the ball valve kit by turning the extension nipple can break the sealing. Tighten the ball valve assembly only from the ball valve body. 4. If you need to cap the ball valve assembly before installing or after removing the probe, attach a blanking nut to close the top of the valve.

Attaching Probe to Indigo 200 Series Transmitter Figure 17 Attaching the Probe to Indigo 200 Series 1. Insert the probe or the connection cable into the transmitter's connector. Use of connection cable is recommended for strain relief. 2. Turn the locking wheel of the transmitter to lock the probe or cable in place. Do not turn the probe or the cable itself, as that will damage the connectors.
Vaisala Insight Software Vaisala Insight software is a configuration software for Indigo-compatible devices. With the Insight software, you can: • See probe information and status • See real-time measurement • Record data up to 48 hours and export in CSV format •...
