We have various type of Pressure Transmitters, which would be selected on the basis of application, details of medium and its max. pressure and Temperature. The basic use of Pressure Transmitter is to Sense the pressure in the process and to give its proportionate output to the device which will either indicate the values in Pressure Terms or it will give some Controlled Output. We have a very common Miniature Pressure Transmitters, Miniature Transmitters with integral Digital Display, Miniature Pressure Transmitter with Integral Bar Graph Display, Pressure Transmitters with integral LCD display, Smart Pressure Transmitters etc. All these transmitters can be provided as Flush Diaphragm type Pressure Transmitter, Pressure Transmitter with Triclover connection, Pressure Transmitter with Remote Diaphragm Seal, Pressure Transmitter with Flange connection, Pressure Transmitter in Flameproof version etc.

We have Vacuum Sensors and Switches for Indication & Control applications. Vacuum Switches & Compound Range Switches are normally used in Vacuum Pumps or, Vacuum based systems where you have to ensure availability of Vacuum within Low & High set limits. So using Vacuum Switches you can control your process in On-Off mode. Vacuum Transmitters are used to know actual availability of Vacuum in the process and the same can be used to read or, control in proportionate or, On-Off mode. Flameproof Vacuum Switch is designed as per IS2148 for Gas Gr. IIC Flameproof - CE Certification and approved by a leading European Lab – “BASEEFA” for ATEX & ICEEX certificates Adjustable Range : 760 to 100 mm Hg Vacuum Diaphragm : Teflon or, Neoprene Pressure Housing MOC : Aluminium, Brass or, SS 316

We have Differential Pressure Gauge with Switches, which are useful in industrial applications like Automatic cleaning systems for Heat Exchangers and various type of expensive Filters. We have few options in the same : Differential Pressure Gauge with one Switch, Differential Pressure Gauge with Duel Switches or, Differential Pressure Gauge with Flameproof Switching contacts. The type of Differential Pressure Gauge with Switches are : Piston type DP Gauge with Switch - These are offered when medium in both the ports are same and slight migration is acceptable. Diaphragm type DP Gauge with Switch - These are recommended where migration of mediums in two ports in not acceptable. & Digital DP Gauge with Switch (Digital DP Indicator with Swicthing contacts) - For high accuracy applications these are recommended..

Adjustable Range : -1.0 to +1.0 bar Enclosure : IP 66 Contact parts : SS 316 & Teflon Compound Pressure range means range coverage from Vacuum up to +ve Pressure. NK Instruments Pvt. Ltd. has Compound range Pressure Switches, which are suggested when the set point is in Vacuum but normally there is +ve pressure in that process Or, vice versa. These switches are available in Weatherproof and Flameproof versions also, as shown below:
